A basic course of the representation theory, which is one of important and powerful theories in mathematics and physics of the 20th century. Notions of Lie groups and Lie algebras are introduced and the relations between these objects, homomorphisms and representations explained. Basic types of Lie algebras (nilpotent, solvable, simple) expalined, major attention is paid to the representations of semisimple algebras. Notions of Cartan subalgebra, weights, roots, used to classify the representations and the algebras. The Clifford algebra is defined and the so-called spinors and the Spin-group

Lie algebra, homomorphisms of Lie algebra. Left-invariant vector fields on Lie groups, Lie algebra of a Lie group, one-parametric subgroups of a Lie group, exponential map. Correspondence between homomorphisms of Lie groups and homomorphisms of Lie algebras. Basic facts on representations of Lie groups and algberas (restrictions of representations, factor-representation, contragredient representation, sum and tensor product of representations, intertwining maps, isomorphism of representations). Irreducible representations of simple Lie algebras (classification of representations of sl(2,C), Cartan subalgebras, roots, positive roots, simple roots, weights, weight lattice, Weyl chambers, dominant weights, fundamental weights). Classification of irreducible representations of four classical series, construction of fundamental representations, spinor representations,. Dynkin diagrams, classification of complex simple Lie algebras.
