Topics: The goal will be to learn the necessary background from algebraic geometry, the theory of linear and arithmetic groups, homology and cohomology, in order to read to reasonable depth the classical paper by A. Borel and J.-P. Serre, Corners and arithmetic groups, Comment. Math. Helv. No.48 (1973), 436-491. I will post the material used to prepare for class and occasionally my own notes on this page. 0) It seems that the paper of Borel and Serre is not available for free download, even with the subscriptions that the University Library owns, but here is apparently a way to read the paper online. On that page, follow the link under "Access Full Article" header. 1) Here is the first post with a great resource on arithmetic groups that contains much much more than we will need and use: Introduction to arithmetic groups by Dave Witte-Morris. The following information is added to satisfy the Minimum Contents of a Class Syllabus requirements. The prerequisites for this course are first year courses in algebra and topology. The course is A-E graded. There is no official textbook. Attendance is critical to success in the class.
