    PUBLIC LECTURE The 1970s saw an explosion in the development of cryptography that vastly expanded the role of number theory in cryptography. Now, that role stands threatened by developments in quantum computing.  We will trace cryptography from its origins to its explosive growth in the 20th century and its contemporary...

    We prove a result about the Galois module structure of the Fermat curve using commutative algebra, number theory, and algebraic topology. Specifically, we extend work of Anderson about the action of the absolute Galois group of a cyclotomic field on a relative homology group of the Fermat curve. By finding explicit formulae for this action, we...

    We investigate in this talk the average root number (i.e. sign of the functional equa- tion) of one-parameter families of elliptic curves (i.e elliptic curves over Q(t), or elliptic surfaces over Q). For most one-parameter families of elliptic curves, the aver- age root number is predicted to be 0. Helfgott showed that under Chowla’s...
