Introduction to Topology

Department of Mathematics, University of Toronto, Fall 2010

Agenda: Understand "continuity" in the most abstract, learn about "the fundamental groups" and maybe touch "surfaces".

Instructor: Dror Bar-Natan, drorbn@math.toronto.edu (Wiki before Email!), Bahen 6178, 416-946-5438. Office hours: by appointment.

Classes: Mondays 2-3 and Thursdays 2-4 in Sydney Smith 1070.

Teaching Assistant: David Reiss, david.reiss@utoronto.ca, SS 622.

Text

James Munkres' Topology. The topology texts by Dugundji and Massey are also recommended, and many other texts are also available. (A useful principle to know is that many math texts are available online. Web search for (name of text + name of author + pdf or djvu).
