## MATH-F310: Differential Geometry I

#### 2021

**Room:** P.OF.2068-2070;
**Time:** Mondays, 10:00-12:30.

**Course content:**This course is the first part of the Differential Geometry course. In particular, basic notions and methods of differential geometry such as smooth manifolds, vector fields, vector bundles etc. appearing both in various branches of mathematics and physics will be introduced and developed.

## MATH-F419: Algebraic topology

#### 2021

**Room and Time:** Wednesdays 10:00-11:00 in P.OF.2078 and Fridays 14:00-15:00 in P.1C3.203.

**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 (Brouwer’s theorem).
