Thursday 24 Oct 2019: NT Seminar: An explicit reciprocity law for the GSp(4)-Euler system
Prof. Sarah Zerbes - UCL
I will report on work in progress with David Loeffler and Chris Skinner. I will sketch a proof for of an explicit reciprocity law for the Euler system attached to the spin representation of genus 2 Siegel modular forms, relating the Euler system to the spin p-adic L-function that we constructed in joint work with Vincent Pilloni. As an application, we obtain bounds on Selmer groups, conditional on the nonvanishing of non-critical p-adic L-values.
