## MATH-F419: Algebraic topology

#### 2022

**Room and Time:** As a rule, Thursdays 10:00-12:00 in P.FORUM.I.2078.

However, 22.09 14:00-16:00 in P.A2.222, 07.11 10:00-12:00 in P.FORUM.I.2078

**Course content:**The idea is to associate to topological spaces algebraic objects (groups, rings etc). If this is done judiciously, one can hope for example to distinguish non-homeomorphic spaces or essentially different continuous maps (in a suitable sense). This in turn allows one to prove interesting results, for example that any continuous map from a closed ball in a finite-dimensional Euclidean space into itself has a fixed point (Brouwerâ€™s theorem).
