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".
Classes: Mondays 2-3 and Thursdays 2-4 in Sydney Smith 1070.
|Teaching Assistant: David Reiss, email@example.com, SS 622.|
James Munkres' Topology (see Errata). 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).

A note from the TA
Hello all. Just a couple points of possible interest for your problem sets. First, they do not need to be extremely detailed or lengthy, however please make sure that you do mention that an argument comes from a theorem or lemma (unless it is very obvious). You can be very concise as long as you reference your arguments like this. A good length you should aim for is 4 pages hand written. It is also a very good exercise to look over a question you have written out and ask yourself what the main arguments you used were. How can I summarize this argument?
I noticed many students have confused the topology with the basis. The basis generates the topology. For example, not all sets in the product topology of XxY are of the form UxV where U is open in X and V is open in Y. (Consider (0,1)x(0,1) union (2,3)x(2,3) <--- open since it is the union of open sets, yet it cannot be expressed as UxV. Draw a picture if this is unclear).
