Herbrand-Ribet Theorem – Ken Willyard

The Herband-Ribet Theorem is an important result in Number Theory that describes a connection between p-part of the class group of Q(mu_p) with Bernoulli numbers. In this mini-talk, I will describe key ideas going into the proof, passing through various aspects of Number Theory including modular forms, Galois representations, and ideal class groups.
