Title: An introduction to absolute integral closure.
Abstract: In this talk we shall introduce the notion of absolute integral
closure of a domain and mention some of its basic properties. Along with
some other results we shall prove the Newton-Puiseux theorem and the fact
that for a powers series ring A of finitely many variables over a field of
positive characteristic, the absolute integral closure of A is flat over
A.
