Doctoral Course in Mathematics
Winter Semester 2003/04
Prof. Kathryn Hess Bellwald
Model category theory, first developed in the late 1960's by Quillen, has become very popular among algebraic topologists and algebraic geometers in the past decade. A model category is a category endowed with three distinguished classes of morphisms -- fibrations, cofibrations and weak equivalences-- satisfying axioms that are properties of the topological category and its usual fibrations, cofibrations and weak equivalences. In any model category there is a notion of homotopy of morphisms, based on the definition of homotopy of continuous maps.
The purpose of this course is to provide an introduction
to model category theory, complete with numerous examples of model
categories and their applications in algebra and topology.
Complete reference details for Hirschhorn's book just added to bibliography!
