Reading Group on Neron Popescu Desingularization


General Information

Meeting Times: Thursday, 11-1pm, SEO 512

Our goal is to prove Popescu's theorem while developing whatever machinery we need along the way. We will follow the treatment in Swan's expository article "Neron Popescu Desingularization." Additional lectures devoted to applications will be interspersed with the main talks.
