Books
There are many books called something like An Introduction to Algebraic Topology or just Algebraic Topology. Any of these will cover most if not all of what you shall see during this course. It's really a matter of personal taste as to which books you prefer. However, a book that is currently very popular (and available for free complete download on the author's website) is that of Hatcher's. Here are some other authors worth a look:
Armstrong;
Bredon;
Dold;
Fulton;
Spanier.
Lectures
Here's a brief outline of what I intend to cover in each week's lectures.
Week |
Content |
1 |
CW-complexes (otherwise known as cell complexes), cellular homology. |
2 |
Examples of cellular homology, beginnings of homological algebra. |
3 |
Simplicial homology, chain complexes in general. |
4 |
Singular homology, functoriality. |
5 |
Homotopy recap, homotopy invariance, using homology as more than just an invariant. |
6 |
Homological algebra, short five lemma, SES of chain groups gives LES of chain complexes. |
7 |
LES of a pair, equivalence of simplicial and singular homology. |
8 |
LES of a pair, equivalence of cellular and singular homology. |
9 |
Mayer-Vietoris, computations, applications. |
10 |
More computations and applications, other coefficient rings. |
Assignments
Solutions to any starred questions are to be handed in to my pigeonhole in the first floor common room in the mathematics department on the due date, or alternatively to me in lecture.
