Title: Vector-valued modular forms and CM Jacobians

Abstract: In this talk, I will explain how vector-valued modular forms

may be used to compute explicitly periods of modular curves, and how the

application of this technique to noncongruence subgroups of the modular

group should soon yield new examples of Jacobians of modular curves with

complex multiplication (i.e., CM Jacobians).

Logic seminar: David Ross
Apr 6 @ 2:30 pm – 3:30 pm

This week in the Logic Seminar in Keller 314, David Ross will give an easy proof of a slight extension of a result of Lagarias on the Diophantine equation

$$c(1/x_1+cdots+1/x_s)+b/(x_1 x_2cdots x_s)=a$$

The proof will be nonstandard, but really only require a sufficiently-saturated ordered field extension of $mathbb R$.
