Lethbridge Number Theory and Combinatorics Seminar: Nathan Ng

In the past twenty years there has been a flurry of activity in the study of mean values of L-functions. This was precipitated by groundbreaking work of Keating and Snaith in which they modelled these mean values by random matrix theory. In this talk I will survey the best known asymptotic results for the mean values of L-functions in certain families (the Riemann zeta function on the half line and/or quadratic Dirichlet L-functions at the central point s=1/2).
