"Low critical zeros of modular (and automorphic) L-functions"
Abstract: We discuss two two instances of the interplay between the statistics of low-lying zeros of L-functions and properties of the associated modular (or automorphic) forms. The first (with SJ Miller) explains the efect on the zero statistics of Rankin-Selberg convolution of the L-functions. The second (in progress with DK Huynh, JP Keating, SJ Miller, NC Snaith) hints at a connection between central zero repulsion and excess rank in families of elliptic curves. In both cases random matrix theory ideas play an important motivational role

"Weak Maass forms, mock theta functions, and applications"
Abstract: The modularity of the partition generating function has many important consequences, for example asymptotics and congruences for p (n). Recently it became clear that the rank, a partition statistic introduced by Dyson, is related to weak Maass forms, a class of functions which are related to modular forms. I want to speak about some of the applications and also discuss higher weight analogues.

"p-adic L-functions for GSp(4)x GL(2)"
Abstract: Let p be an odd prime. In this talk we will construct a p-adic analog of a degree eight L-function L(s, F×f) where F is an ordinary holomorphic degree 2 Siegel eigen cusp form of level a power of p and f is an ordinary eigen cusp form of level a power of p. Our method makes use of the work of M. Furusawa which gives an integral representation for this L-function. By suitably interpreting this integral representation in the context of inner products of automorphic forms, we show that it p-adically interpolates the L-values as the forms F and f vary in ordinary families (with the weights varying p-adically). This interpolation is carried out by constructing an Eisenstein measure on a higher-rank unitary group and exploiting a pull-back formula of P. Garrett and G. Shimura.

"On the Fourier inversion formula for reductive groups"
We demonstrate a new proof of the Fourier inversion formula for the continuous spectrum in L2(SL2(Z)\SL2(R)/SO2(R)). Although this proof assumes the meromorphic continuation of the Maass- Eisenstein series, it avoids a contour shift that increases in complexity when generalizing to reductive groups of higher rank.

11:30-12:00 Frank Thorne (UW-Madison)
"Bounded Gaps between Products of Primes with Applications to Elliptic Curves and Ideal Class Groups"
Abstract: In recent work, Goldston, Pintz, and Yildirim proved that $\liminf (p_{n + 1} - p_n) / \log p_n = 0$. (Here $p_n$ denotes the nth prime.) In follow-up work with S. Graham, they also proved the existence of bounded gaps between products of two primes. Generalizing their work, we will present a similar bound for products of $r$ primes, for any $r \geq 2$, which covers the case when these primes are restricted to any Chebotarev set. As a consequence, we will obtain "bounded gaps" results concerning class numbers, Fourier coefficients of modular forms, and ranks of elliptic curves.
