Title: On level raising modulo prime powers
Abstract: In this talk, we will discuss the problem of raising the level of classical cuspidal eigenforms modulo prime powers (for odd primes) of weight k≥ 2 and arbitrary character. The main result we will present extends previous results in weight 2 established by Tsaknias and Wiese and it will generalize (partially) Diamond’s and Ribet's celebrated level raising theorems.
The talk will take place on Zoom. If you would like to receive the Zoom link and are not part of our current NT Seminar mailing list, please contact the organizer.
