Complex Geometry

65-417 Lie algebras

Lecturer: Pawel Sosna
Time and place: Lecture: Tuesdays 12:15-13:45 in room 1240 and Fridays 10:15-11:45 in room 432
Recitations: every other Friday 10:15-11:45 in room 432
Content: A Lie algebra is a vector space endowed with a non-associative multiplication called Lie bracket. These objects are closely related to certain manifolds and are relevant in several areas of mathematics and mathematical physics. The purpose of the lecture is to give an introduction to Lie algebras and their representation theory. In particular, we will study ideals, homomorphisms, solvable, simple and nilpotent Lie algebras and, if time permits, try to understand the classification of simple complex Lie algebras via their root systems.
Prerequisites: The main prerequisite for the course is a good understanding of linear algebra (that is, Lineare Algebra I and II). Some familiarity with basic concepts from algebra (rings, ideals,...) might be useful. The lecture is suitable for students from the 4th semester on.
