The course is divided in two parts. Joyal’s CatLab nLab Scanned lecture notes: Since then, model categories have become one a very important concept in algebraic topology and have found an increasing number of applications in several areas of pure mathematics. This subject has received much attention in recent years due to new foundational work of VoevodskyFriedlanderSuslinand others resulting in the A 1 homotopy theory for quasiprojective varieties over a field.

Algebraic topology Topological methods of algebraic geometry Geometry stubs Topology stubs. Some familiarity with topology. The subject of homotopical algebra originated with Quillen’s seminal monograph [1], in which he introduced the notion of a model category and used it to develop an axiomatic approach to homotopy theory.

A preprint version is available from the Hopf archive. The aim of this course is to give an introduction to the theory of model categories. The second part will deal with more advanced topics and its content will depend on the audience’s interests. Lecture 3 February 12th, Outline of the Hurewicz model structure on Top.
