Course description >
This course offers an introduction to algebraic topology, that is, the study of topological spaces by means of algebra. The first part of the course focuses on homology theory. Singular homology groups are algebraic invariants of spaces: for every space there are such groups and every map of spaces induces a map between the corresponding groups. These invariants turn out to be rather computable, and they allow for some immediate geometric applications. We will establish some key properties of these homology groups like the homotopy invariance and the excision theorem.
A convenient variant is provided by singular homology with coefficients a framework which makes necessary a short discussion of basic homological algebra including tensor and torsion products. For CWcomplexes, there is also the more combinatorial cellular homology theory. The course culminates in a proof that singular homology and cellular homology agree on CWcomplexes. This allows for more explicit calculations in examples of interest (e.g., projective spaces).
