... We will start the study of integral closure from the definition and we will aim to Rees’s characterization of analytically unramified rings and the Brianson-Skoda Theorem. I will try to make the class as self-contained as possible. People should be familiar with the content of Introduction to Commut ...

This new equivalence relation is open, since for each open subset U of X, the e are equal. saturated sets of U , by G and by G, e the orbit class space, q : X → We denote by X/G the orbit space, X/G e the canonical projections. The orbit class space is X/G and p : X → X/G introduced and studied in [ ...
