Title: Sums of the divisor function and random matrix distributions

Abstract: The divisor function gives the number of positive divisors of a natural number. How can we go about understanding the behavior of this function when going over the natural numbers? In this talk we will discuss strategies to better understand this function, issues related to the distribution of these values, and connections to the Riemann zeta function and some groups of random matrices. This talk includes joint work with Vivian Kuperberg.
