Lectures on Homotopy Theory

J.F.Jardine

The links below are to pdf files, which comprise the lecture notes for a course on Homotopy Theory.

This collection of files is the basic source material for the course, and the syllabus is listed on this page. All files are subject to revision as the course progresses. 

More detail on topics covered here can be found in the Goerss-Jardine book Simplicial Homotopy Theory, which appears in the References file below.

The course will be given as a set of lectures at the University of Western Ontario, and will be available by video conference to students from other universities. Students from other sites can participate, from either traditional video conference rooms or by using personal computers. Please contact me if you wish to do so.

It would be quite helpful for a student to have a background in basic Algebraic Topology (our course Math 4152/9052) and/or Homological Algebra (our Math 9144) prior to taking this course.
