Text: Our main text will be
Hatcher's text includes all the algebraic topology that we will cover in 752. For the differential topology, I recommend
Of course, as with most graduate classes, there is a wealth of other relevant texts that you may find useful:
Description:  The first half of the class will be mostly algebraic topology, as we develop the homological algebra necessary to study and compute cohomology. The relevant theorems are the Universal Coefficient and Kunneth theorems. We then study cup and cap products in (co)homology. The big theorem here is an application to the study of manifolds: Poincare duality.

This leads us to the more geometric part of the course: we study differential forms and integration on manifolds. We connect to the first half of the course by interpreting these constructions in terms of (deRham) cohomology: cup products of cohomology classes correspond to wedge products of forms and cap products correspond to integration (leading to a geometric description of Poincare duality). The deRham theorem is the major tool for these comparisons.

Finally, we round out the semester with fixed point theorems (especially the Lefschetz fixed point theorem), and more duality theorems (e.g. Alexander duality). If there is time, we'll move on to bundle theory and characteristic classes.

Grading: There will be homework (collected every week) and a (take home) final exam given the final week of classes.  The homework will account for 60% of the grade, and the final will account for 40%.

Homework: All problems are taken from Hatcher unless otherwise indicated.  Note: one should take the problems from the version of Hatcher that is available online (with errors corrected).
