'''Categorical Enumerative Invariants'''<br />
<br />
I will talk about recent papers with Junwu Tu, Si Li, and Kevin Costello where we give a computable definition of Costello's 2005 invariants and compute some of them. These invariants are associated to a pair (A,s) consisting of a cyclic A∞-algebra and a choice of splitting s of its non-commutative Hodge filtration. They are expected to recover classical Gromov-Witten invariants when A is obtained from the Fukaya category of a symplectic manifold, as well as extend various B-model invariants (solutions of Picard-Fuchs equations, BCOV invariants, B-model FJRW invariants) when A is obtained from the derived category of a manifold or a matrix factorization category.<br />

'''Singular support of categories'''<br />
<br />
In many situations, geometric objects on a space have some kind of singular support, which refines the usual support.<br />
For instance, for smooth X, the singular support of a D-module (or a perverse sheaf) on X is as a conical subset<br />
of the cotangent bundle; there is also a version of this notion for coherent sheaves on local complete intersections.<br />
I would like to describe a higher categorical version of this notion.<br />
<br />
Let X be a smooth variety, and let Z be a closed conical isotropic subset of the cotangent bundle of X. I will define a<br />
2-category associated with Z; its objects may be viewed as `categories over X with singular support in Z'. In particular, if Z is<br />
the zero section, this gives the notion of categories over Z in the usual sense.<br />
<br />
The project is motivated by the local geometric Langlands correspondence; I will sketch the relation with the Langlands correspondence without <br />
going into details.<br />

'''Harmonic Analysis on GLn over Finite Fields'''<br />
<br />
There are many formulas that express interesting properties of a finite group G in terms of sums over<br />
its characters. For estimating these sums, one of the most salient quantities to understand is the character ratio:<br />
Trace(ρ(g)) / dim(ρ), for an irreducible representation ρ of G and an element g of G. For example, Diaconis<br />
and Shahshahani stated a formula of the mentioned type for analyzing certain random walks on G. Recently,<br />
we discovered that for classical groups G over finite fields there is a natural invariant of representations that<br />
provides strong information on the character ratio. We call this invariant rank. Rank suggests a new<br />
organization of representations based on the very few “Small” ones. This stands in contrast to Harish-Chandra’s<br />
“philosophy of cusp forms”, which is (since the 60s) the main organization principle, and is based on the (huge<br />
collection) of “Large” representations. This talk will discuss the notion of rank for the group GLn over finite<br />
fields, demonstrate how it controls the character ratio, and explain how one can apply the results to verify<br />
mixing time and rate for random walks. This is joint work with Roger Howe (Yale and Texas A&M). The<br />
numerics for this work was carried with Steve Goldstein (Madison) and John Cannon (Sydney).<br />

'''The Supermoduli Space of Genus Zero SUSY Curves with Ramond Punctures<br />
<br />
Super Riemann surfaces (SUSY curves) arise in the formulation of superstring theory, and their moduli spaces, called supermoduli space, are the integration spaces for superstring scattering amplitudes. I will focus specifically on genus zero SUSY curves. As with ordinary curves, genus zero SUSY curves present a certain challenge, as they have an infinitesimal group of automorphisms, and so in order for the moduli problem to be representable by a Deligne-Mumford superstack, we must introduce punctures. In fact, there are two kinds of punctures on a SUSY curve of Neveu-Schwarz or Ramond type. Neveu-Schwarz punctures are entirely analogous to the marked points in ordinary moduli theory. By contrast, the Ramond punctures are more subtle and have no ordinary analog. I will give a construction of the moduli space M_{0,n}^R of genus zero SUSY curves with Ramond punctures as a Deligne-Mumford superstack by an explicit quotient presentation (rather than by an abstract existence argument).<br />

'''A Rogers-Ramanujan-Slater type identity related to the Ising model'''<br />
<br />
We prove three new q-series identities of the Rogers-Ramanujan-Slater<br />
type. We find a PBW basis for the Ising model as a consequence of one of these<br />
identities. If time permits it will be shown that the singular support of the<br />
Ising model is a hyper-surface (in the differential sense) on the arc space of<br />
it's associated scheme. This is joint work with G. E. Andrews and J. van Ekeren<br />
and is available online at https://arxiv.org/abs/2005.10769</div>Arinkinhttps://www.math.wisc.edu/wiki/index.php?title=Algebra_and_Algebraic_Geometry_Seminar_Fall_2020&diff=19819Algebra and Algebraic Geometry Seminar Fall 20202020-09-15T16:47:59Z<p>Arinkin: /* Dima Arinkin */</p>

'''Categorical Enumerative Invariants'''<br />
<br />
I will talk about recent papers with Junwu Tu, Si Li, and Kevin Costello where we give a computable definition of Costello's 2005 invariants and compute some of them. These invariants are associated to a pair (A,s) consisting of a cyclic A∞-algebra and a choice of splitting s of its non-commutative Hodge filtration. They are expected to recover classical Gromov-Witten invariants when A is obtained from the Fukaya category of a symplectic manifold, as well as extend various B-model invariants (solutions of Picard-Fuchs equations, BCOV invariants, B-model FJRW invariants) when A is obtained from the derived category of a manifold or a matrix factorization category.<br />

'''Harmonic Analysis on GLn over Finite Fields'''<br />
<br />
There are many formulas that express interesting properties of a finite group G in terms of sums over<br />
its characters. For estimating these sums, one of the most salient quantities to understand is the character ratio:<br />
Trace(ρ(g)) / dim(ρ), for an irreducible representation ρ of G and an element g of G. For example, Diaconis<br />
and Shahshahani stated a formula of the mentioned type for analyzing certain random walks on G. Recently,<br />
we discovered that for classical groups G over finite fields there is a natural invariant of representations that<br />
provides strong information on the character ratio. We call this invariant rank. Rank suggests a new<br />
organization of representations based on the very few “Small” ones. This stands in contrast to Harish-Chandra’s<br />
“philosophy of cusp forms”, which is (since the 60s) the main organization principle, and is based on the (huge<br />
collection) of “Large” representations. This talk will discuss the notion of rank for the group GLn over finite<br />
fields, demonstrate how it controls the character ratio, and explain how one can apply the results to verify<br />
mixing time and rate for random walks. This is joint work with Roger Howe (Yale and Texas A&M). The<br />
numerics for this work was carried with Steve Goldstein (Madison) and John Cannon (Sydney).<br />

'''A Rogers-Ramanujan-Slater type identity related to the Ising model'''<br />
<br />
We prove three new q-series identities of the Rogers-Ramanujan-Slater<br />
type. We find a PBW basis for the Ising model as a consequence of one of these<br />
identities. If time permits it will be shown that the singular support of the<br />
Ising model is a hyper-surface (in the differential sense) on the arc space of<br />
it's associated scheme. This is joint work with G. E. Andrews and J. van Ekeren<br />
and is available online at https://arxiv.org/abs/2005.10769</div>Arinkinhttps://www.math.wisc.edu/wiki/index.php?title=File:Math764hw10.pdf&diff=19383File:Math764hw10.pdf2020-04-26T20:06:31Z<p>Arinkin: Arinkin uploaded a new version of File:Math764hw10.pdf</p>

== Course description ==<br />
<br />
This course is the continuation of Math 763. The goal is to put to extend the framework of algebraic geometry from varieties (studied in Math 763) to schemes. This requires using the language of sheaves (and, particularly, sheaves of rings) on topological spaces.<br />
<br />
We will start with the Riemann-Roch Theorem and the related topics (divisors, projective embeddings). Then we will go over basic properties of sheaves, and define schemes and morphisms of schemes. <br />

This course is the continuation of Math 763. The goal is to put to extend the framework of algebraic geometry from varieties (studied in Math 763) to schemes. This requires using the language of sheaves (and, particularly, sheaves of rings) on topological spaces.<br />
<br />
In the beginning of the course, we will go over basic properties of sheaves. We will then define schemes and morphisms of schemes, and study various classes of morphisms. Time permitting, I hope to discuss more interesting topics, such as (quasi)coherent sheaves on schemes and moduli spaces.<br />

== Course description ==<br />
<br />
This is a first course in algebraic geometry. While there are no formal prerequisites beyond a knowledge of the material covered in the first-year algebra and geometry sequence, familiarity with some basic commutative algebra will be helpful. The rough outline of the course is as follows (subject to change):<br />
<br />
* Affine and projective varieties.<br />
* Morphisms and rational maps.<br />
* Local properties: smoothness and dimension. Tangent space.<br />
* Divisors.<br />
* Low-dimensional varieties: curves and surfaces. Blow-ups.<br />
* The Riemann-Roch Theorem.<br />
<br />
Here is a more detailed lecture-by-lecture [[Math 763 -- Algebraic Geometry I -- Detailed list of topics|list of topics]] that I covered in the past, of course, this is all subject to change.<br />

<br />
The Putnam Exam, offered by the Mathematical Association of America, is the premier American math competition for undergraduate students. It is given each year on the first Saturday in December. The exam consists of 12 problems, 6 in the 3 hour morning session and 6 in the 3 hour afternoon session. Each problem is worth 10 points, so the maximum score is 120. National winners usually get around 100 points. The median score is generally around 0-2 points. This is a difficult exam with many interesting and fun problems.<br />
<br />
[http://kskedlaya.org/putnam-archive/ Old exams and more information on the Putnam competition.]<br />
<br />
The UW is also participating in the Virginia Tech Regional Mathematics Contest. This is an individual competition with seven problems in 2.5 hours. Many schools use it as a kind of rehearsal for the Putnam. You can find more information [http://intranet.math.vt.edu/people/plinnell/Vtregional/ over here.]<br />
<br />
We also hold our own UW Madison [[Undergraduate Math Competition]] in the spring; for this academic year, it is tentatively scheduled in April 2019.<br />
<br />
The Virginia Tech Regional Mathematics Contest is on Oct 26, 9:00-11:30am at Van Vleck Hall B123. [https://docs.google.com/forms/d/e/1FAIpQLSfLFgT77SQxbZYN-vQUktsSsekWWITvLf0oiNOYxjCD55oIkg/viewform?usp=sf_link/ Please click this link to register. ]<br />

The Putnam Club will help you prepare for the exam by practicing on problems from previous years and other olympiad-style problems. The meeting time is 5pm on Wednesdays in VV B139. '''The first meeting will be on the 25th of September in Van Vleck hall, room B139.'''<br />
<br />
We will continue using the [http://piazza.com/wisc/fall2018/putnam2018/ Piazza page] from last semester for discussions. The book we will mainly use as a guide in preparing our meetings is: "Putnam and Beyond" by Razvan Gelca and Titu Andreescu. <br />

<br />
'''! Important announcement:''' We will begin preparing you for the Putnam exam earlier this year. The material covered will be presented gradually. More details will be explained to you during your first meeting of this semester (Feb 6th). We put together a Piazza account that will help the participants to discuss and collaborate with their pairs. Here is the link you need to access in order to register for this "class": piazza.com/wisc/fall2018/putnam2018 . Our intervention on Piazza will be minimal (some of the instructors will, from time to time, visit the piazza questions and provide some help). Also, based on your requests, we have decided to structure our meetings in a way that will provide more insight on methods and certain tricks that are very often used in this type of math competitions. The book we will mainly use as a guide in preparing our meetings is: "Putnam and Beyond" by Razvan Gelca and Titu Andreescu. <br />

If this material is completely new to you then read through the definitions in the first section and try the interspersed exercises which are direct applications of the definitions. If you are familiar with the basic material then review the problem solving strategies and the example problems which directly utilize the techniques. Finally, if you are a veteran, go ahead and jump right to the exercises!<br />

You should arrive at least 10 minutes prior to each session. You should bring your own pencils and pens (blue or black ink are permitted). Number 2 pencils with erasers will be needed to complete the identification forms. Erasers are also permitted, but nothing else will not be allowed in the exam room. I plan on bringing 20 such no 2 pencils. The exam room is B239 which is a class room located in Van Vleck Hall, at the level B2. Thank you all for participating and see you all there! If you have friends that would like to take the exam please encourage them to do so.'''<br />

<br />
The Putnam Exam, offered by the Mathematical Association of America, is the premier American math competition for undergraduate students. It is given each year on the first Saturday in December. The exam consists of 12 problems, 6 in the 3 hour morning session and 6 in the 3 hour afternoon session. Each problem is worth 10 points, so the maximum score is 120. National winners usually get around 100 points. The median score is generally around 0-2 points. This is a difficult exam with many interesting and fun problems.<br />
<br />
[http://kskedlaya.org/putnam-archive/ Old exams and more information on the Putnam competition.]<br />
<br />
The UW is also participating in the Virginia Tech Regional Mathematics Contest. This is an individual competition with seven problems in 2.5 hours. Many schools use it as a kind of rehearsal for the Putnam. You can find more information [http://intranet.math.vt.edu/people/plinnell/Vtregional/ over here.]<br />
<br />
We also hold our own UW Madison [[Undergraduate Math Competition]] in the spring; for this academic year, it is tentatively scheduled in April 2019.<br />
<br />
The Virginia Tech Regional Mathematics Contest is on Oct 26, 9:00-11:30am at Van Vleck Hall B123. [https://docs.google.com/forms/d/e/1FAIpQLSfLFgT77SQxbZYN-vQUktsSsekWWITvLf0oiNOYxjCD55oIkg/viewform?usp=sf_link/ Please click this link to register. ]<br />

The Putnam Club will help you prepare for the exam by practicing on problems from previous years and other olympiad-style problems. The meeting time is 5pm on Wednesdays in VV B139. '''The first meeting will be on the 25th of September in Van Vleck hall, room B139.'''<br />
<br />
We will continue using the [http://piazza.com/wisc/fall2018/putnam2018/ Piazza page] from last semester for discussions. The book we will mainly use as a guide in preparing our meetings is: "Putnam and Beyond" by Razvan Gelca and Titu Andreescu. <br />

The Putnam Club will help you prepare for the exam by practicing on problems from previous years and other olympiad-style problems. The meeting time is 5pm on Wednesdays in VV B139. The first meeting will be on the 6th of February in Van Vleck hall, room B139.<br />
<br />
'''! Important announcement:''' We will begin preparing you for the Putnam exam earlier this year. The material covered will be presented gradually. More details will be explained to you during your first meeting of this semester (Feb 6th). We put together a Piazza account that will help the participants to discuss and collaborate with their pairs. Here is the link you need to access in order to register for this "class": piazza.com/wisc/fall2018/putnam2018 . Our intervention on Piazza will be minimal (some of the instructors will, from time to time, visit the piazza questions and provide some help). Also, based on your requests, we have decided to structure our meetings in a way that will provide more insight on methods and certain tricks that are very often used in this type of math competitions. The book we will mainly use as a guide in preparing our meetings is: "Putnam and Beyond" by Razvan Gelca and Titu Andreescu. <br />

If this material is completely new to you then read through the definitions in the first section and try the interspersed exercises which are direct applications of the definitions. If you are familiar with the basic material then review the problem solving strategies and the example problems which directly utilize the techniques. Finally, if you are a veteran, go ahead and jump right to the exercises!<br />

You should arrive at least 10 minutes prior to each session. You should bring your own pencils and pens (blue or black ink are permitted). Number 2 pencils with erasers will be needed to complete the identification forms. Erasers are also permitted, but nothing else will not be allowed in the exam room. I plan on bringing 20 such no 2 pencils. The exam room is B239 which is a class room located in Van Vleck Hall, at the level B2. Thank you all for participating and see you all there! If you have friends that would like to take the exam please encourage them to do so.'''<br />

== Course description ==<br />
<br />
This is a first course in algebraic geometry. While there are no formal prerequisites beyond a knowledge of the material covered in the first-year algebra and geometry sequence, familiarity with some basic commutative algebra will be helpful. The rough outline of the course is as follows (subject to change):<br />
<br />
* Affine and projective varieties.<br />
* Morphisms and rational maps.<br />
* Local properties: smoothness and dimension. Tangent space.<br />
* Divisors.<br />
* Low-dimensional varieties: curves and surfaces. Blow-ups.<br />

== Abstracts ==<br />

===Yuki Matsubara===<br />
'''On the cohomology of the moduli space of parabolic connections'''<br />
<br />
We consider the moduli space of logarithmic connections of rank 2<br />
on the projective line minus 5 points with fixed spectral data.<br />
We compute the cohomology of such moduli space, <br />
and this computation will be used to extend the results of <br />
Geometric Langlands correspondence due to D. Arinkin <br />
to the case where the this type of connections have five simple poles on ${\mathbb P}^1$.<br />
<br />
In this talk, I will review the Geometric Langlands Correspondence <br />
in the tamely ramified cases, and after that, <br />
I will explain how the cohomology of above moduli space will be used.<br />
<br />
===Juliette Bruce===<br />
'''Semi-Ample Asymptotic Syzygies'''<br />
<br />
I will discuss the asymptotic non-vanishing of syzygies for products of projective spaces, generalizing the monomial methods of Ein-Erman-Lazarsfeld. This provides the first example of how the asymptotic syzygies of a smooth projective variety whose embedding line bundle grows in a semi-ample fashion behave in nuanced and previously unseen ways.<br />
<br />
<br />
===Michael Kemeny===<br />
'''The geometric syzygy conjecture'''<br />
<br />
A famous classical result of M. Green asserts that the ideal sheaf of a canonical curve is generated by quadrics of rank four. Extending this to higher relations, one arrives at the so-called <br />
Geometric Syzygy Conjecture, stating that extremal linear syzygies are spanned by those of the lowest possible rank. This conjecture further provides a geometric interpretation of Green's conjecture <br />
for canonical curves. In this talk, I will outline a proof of the Geometric Syzygy Conjecture in even genus, based on combining a construction of Ein-Lazarsfeld with Voisin's approach to the study of <br />
syzygies of K3 surfaces.<br />
<br />
