Speaker: Ben Lundell of University of Washington
Title: New Parts of Hecke Rings
Abstract: This talk will be an introduction to the concept of
congruences of modular forms . We will give some basic definitions and
examples and then talk about various ways to measure how many
congruences a given modular form satisfies. Finally, we will present
some joint work with Ravi Ramakrishna which is an attempt to determine
"how often" one should expect to find "extra" congruences.
