Title: Fluctuations in the distribution of Hecke eigenvalues
Abstract: A famous conjecture of Sato and Tate (now a celebrated theorem of Taylor et al) predicts that the normalised p-th Fourier coefficients of a non-CM Hecke eigenform follow the semicircle distribution as we vary the primes p. In this talk, we address a situation in which we study the fluctuations in the distribution of these Fourier coefficients about the Sato-Tate measure. This is done by averaging over families of Hecke-eigenforms of weight k. By imposing suitable conditions on the growth of the weight k, these fluctuations are shown to asymptotically follow a Gaussian distribution. This is joint work with Kaneenika Sinha.

Title: Semi-Invariants of Quivers
Abstract: In this talk, I will give an introduction to semi-invariants of quivers, a topic linking representation theory to invariant theory. I will define the ring of semi-invariants of a quiver and explain how one could get a nice set of generators of this ring, using representation theory. If time permits, we will look at some cases where such rings are completely understood. For most of the talk, only basic linear algebra is required.
