Short Intensive course

**Course Title:**

Traid groups and their representations.

**Resource Person: **Christian Blanchet

**Abstract:**

The purpose of the course is to study representations of classical braid groups and to introduce to representations of braid groups of surfaces. We will give the basic definitions, develop algebraic topology constructions, and introduce to quantum representations.

**Schedule:**

Starting from Feb 25th 2019.

The course will comprise on 3 lectures (each of 2 hours duration) on

Monday, Wednesday at 14:00-16:00 and Friday 14:30-16:30.

**Prerequisites:**

Knowledge on basic algebraic topology: fundamental group, homology.

**Who can attend: **
