## FRG Grad SeminarThis is the webpage for the grad seminar of the focused research group on averages of \(L\)-functions and arithmetic stratification funded by the NSF grant DMS-1854398, centered at the American Institute of Mathematics. This is an online seminar aimed at early career researchers in the FRG, though senior researchers often attend. If you would like to volunteer to give a talk, or you would like to attend the seminar, please send me an email. For the past and future schedule, please see below. For the notes and recordings of past talks, please see the sidebar. ## Final Talk [29-Apr-2024]## Brian Conrey (AIM)## Averages of L-functions and arithmetic stratification: a report on the FRGAbstract: I will give an update on some of the work that has been done since the FRG started. ##
