Putnam Exam Results Highlight Excellence at UW


The UW-Madison Department of Mathematics participated in the national annual Putnam Exam this fall.  Sivakorn Sanguanmoo received an honorable mention, which is a very high honor on this competitive test.  There was a team of 3 students from the UW that scored in the top 200, containing Chenghui Li, Liwei Jiang, and Sivakorn Sanguanmoo. Another team, Mingxuan Wu, Tairan Ma, Ruiting Tong, and Xiaxin Li scored in the top 500.

 The William Lowell Putnam Mathematical Competition is the preeminent undergraduate mathematics competition in the United States and Canada. Each year on the first Saturday in December, more than 4,000 students spend two 3-hour sessions solving 12 problems.

Roch named as Vilas Associate


Congratulations to Sebastien Roch for being named as a Vilas Associate.  The Vilas Associates Competition recognizes new and on-going research of the highest quality and significance.  We are proud to see Sebastien being recognized for his excellent research.

UW–Madison mathematicians named Simons Fellows


Three professors at the University of Wisconsin–Madison are among the 2019 class of Simons Fellows in Mathematics.  Gheorghe Craciun, Autumn Kent and Andreas Seeger are among the 48 distinguished scientists named to fellowships.

Each year, the Simons Foundation selects as many as 50 fellows conducting research in math and the physical sciences, providing funding for an academic leave from a term to a full year. The support, according to the foundation, is meant to help recipients “focus solely on research for the long periods often necessary for significant advances.”   Founded in 1994 by Jim and Marilyn Simons, the Simons Foundation supports basic scientific research undertaken in the pursuit of understanding the phenomena of our world.

Gheroghe Craciun
Craciun, a professor of mathematics and biomolecular chemistry, studies mathematical and computational methods for understanding properties of the biochemical networks in cells, like those that regulate gene expression, send signals and manage metabolism.

Autumn Kent
Kent, an associate professor of mathematics, likes to work at the intersection of fields — studying families of geometric objects through hyperbolic geometry, topology and group theory.

Andreas Seeger
Seeger, a professor of mathematics, works in harmonic analysis. His research interests include problems on wave propagation, singular and oscillatory integrals, Fourier and spectral multipliers, and function spaces.

In Memoriam: Terry Millar


Terry Millar died on Saturday, March 9 after a long battle with cancer.  Terry was a faculty member in the Math Department since 1976, retiring in 2015.

After dropping out of college to join the Marines for two years (including a brief stint as forward artillery observer in Vietnam), Terry started graduate school at Cornell and received his PhD in 1976 with Anil Nerode (twenty years his elder and still not retired!).

During the 1980’s, Terry was one of the world’s foremost researchers in computable model theory, an area which had been started by the Novosibirsk school of algebra and logic under Mal’cev and Ershov as well as, in the West, work of Fröhlich and Shepherdson, Rabin, and Nerode; and for a decade, Terry and Goncharov from Novosibirsk, both with coauthors, ended up proving the same results independently and almost simultaneously, but leaving many questions open to the current day.

In the late 1980’s, computable model theory fell briefly out of fashion, and Terry remembered his other great talent, administration, first serving for many years as Associate Dean in the Graduate School and finally as assistant to the Provost. He also became heavily involved in mathematics education and teacher training and was in charge of large grants for multiple school districts across the country, including Madison’s.

A few semesters before his retirement, Terry returned full time to the math department and revived in particular our history of mathematics course (using his unique expertise in both physics and logic).

He will be greatly missed in the department, and we mourn with his family this loss.

Memorial celebration of Terry's life

Terry's family, with guidance from a minister at the First Unitarian Society of Madison and help from many friends, invite all to a memorial to celebrate Terry’s life. This event will be on...

Swimming microbes steer themselves into mathematical order


Saverio Spagnolie and Arthur Evans of UW–Madison, University of Michigan physicist Christopher Miles and mathematician Michael Shelley of the Flatiron Institute and New York University found that when the particles are confined to a thin sheet and allowed to expand into an empty fluid, the collective motion can be described by equations already used in entirely different classical problems in fluid mechanics. The group published its findings recently in the journal Physical Review Letters.
