Approximating the mean square of the product of the Riemann zeta function with Dirichlet polynomials |
Understanding the asymptotics of the mean square of the product of the Riemann zeta function with Dirichlet polynomials allows one to understand the distribution of values of L-functions. I will introduce the problem and describe several results from the paper of Bettin, Chandee and Radziwill who showed how to pass the so called [math]\theta=1/2[/math] barrier for arbitrary Dirichlet polynomials. This will be a prep talk for Thursdays seminar. |

Representations of [math]GL_n(\mathbb{F}_q)[/math] |
I will discuss the irreducible representations of [math]GL_n(\mathbb{F}_q)[/math]. In particular, I will discuss some ways in which we can understand the structure of representations of [math]GL_n(\mathbb{F}_q)[/math] , such as parabolic inductions, Hopf algebra structure, and tensor ranks of representations. This is a preparatory talk for the upcoming talk on Thursday. |

The integrality of the j-invariant on CM points |
The j-function, a complex valued function whose inputs are elliptic curves over [math]\mathbb{C}[/math], classifies the isomorphism class of such elliptic curves. We show that, on elliptic curves with complex multiplication (CM), the j-function takes values which are algebraic integers. |
