### AWM-AMS Noether Lecture – The Power of Noether’s Ring Theory in Understanding Singularities of Complex Algebraic Varieties

#### Karen E. Smith, University of Michigan

##### Introduction: Irena Swanson, Reed College

In one of the tremendous innovations of twentieth century mathematics, Emmy Noether introduced the rigorous definition of commutative rings and their homomorphisms. One of her main motivating examples was the ring of polynomial functions on a complex algebraic variety. The algebraic study of these rings can have deep geometric consequences for the corresponding variety. In this talk, I hope to explain one example of this phenomenon: namely, how reduction to prime characteristic can give us insight into the singularities of the corresponding algebraic variety. Of course, I will need to convince you that we gain something powerful in reducing modulo p, since we have given up all the tools of analysis in doing so. What we gain is the Frobenius operator on the ring, which raises elements to their *p*-th powers, and is a ring homomorphism in characteristic p. I hope to explain how the Frobenius operator is helpful in understanding the singularities. As an application, I will describe some work with Angelica Benito, Jenna Rajchgot and Greg Muller on the singularities of varieties that arise in the theory of cluster algebras in combinatorics.
