# Introduction to Lie Groups Autumn 2018

Lecturer
Marc Burger
Coordinator
Alessio Savini

## Goals of the course

The goal is to have a broad though foundational knowledge of the theory of Lie groups and their associated Lie algebras with an emphasis on the algebraic and topological aspects of it.

## Brief description

The topics included in the course are:
1. Topological groups and Haar measure.
2. Definition of Lie groups.
3. Examples of local fields and examples of discrete subgroups.
4. Lie subgroups.
5. Lie algebras and relation with Lie groups: exponential map, adjoint representation.
6. Semisimplicity, nilpotency, solvability, compactness: Killing form, Lie's and Engel's theorems.
7. Definition of algebraic groups and relation with Lie groups.

## Prerequisites

Topology and basic notions of measure theory. A basic understanding of the concepts of manifold, tangent space and vector field is useful, but could also be achieved throughout the semester.

Exercise sessions take place on Thursdays (every second week) in HG D 3.2 from 8.00 to 10.00. The first exercise session will be on the 27th of september.

The exercise sheet will be uploaded on this page every Tuesday before the exercise session. From that moment the student has to hand in the exercises in room J 68 within 9 days. The corrected exercises are left in the same room.
