# Introduction to algebraic topology, fall 2011

### Lecturer

Aleksandr Pasharin

### Scope

10 cu.

### Type

Advanced studies

### Prerequisites

Topology II, Algebra I, Linear Algebra I.

### Contents

The course is intended to be the first introduction to the singular homology theory and homological methods in algebraic topology.

We start off with the brief excursion to the world of simplices, simplicial methods and Delta-complexes. Then we move on to the main subject of the course - construction of the singular homology theory. We go through all the essential properties of the singular homology and apply it to prove the classical topological results such as the Invariance of Domain, Brouwer's fixed-point theorem, Brouwer-Jordan separation theorem, the main theorem of Algrebra and others.
