M-theory and topology

he Dirichlet series for the reciprocal of the Riemann zeta function

Paul Bateman (UIUC)

Abstract: We consider the behavior of the partial sums of the series $\sum \mu(n)n^{-s}$ for real values of s greater than 1. The talk is related to my recent problem in the American Mathematical Monthly, which deals with some simple cases.

On Bergman's questions, Rourke's extension of group presentations and a version of the Andrews-Curtis conjecture

Sergei Ivanov (UIUC Math)

Abstract: First we finish last week's discussion of positive laws in groups and solution of Bergman's questions on laws in groups of fractions. Then Rourke's extension of group presentations and a version of the Andrews-Curtis conjecture will be discussed.

Tight Closure and Its Applications (I)

Jinjia Li   [email] (UIUC Math)

Abstract: This is the first one of a series of talks focusing on working through Hochster and Huneke's paper "Tight Closure, Invariant Theory, and Briancon-Skoda Theorem". In this talk, we will introduce some basic definitions and properties regarding tight closure followed by proving that a regular ring of characteristic p is F-regular.
