Aims

Representation theory is one of the standard tools used in the investigation of finite groups, especially via the character of a representation.  This module will be an introduction to these ideas with emphasis of the calculation of character tables for specific groups.


Learning Outcomes

(LO1) To use representation theory as a tool to understand finite groups.

(LO2)  To be able to calculate character tables of a variety of groups.

(S1) Problem solving skills

(S2) Numeracy


Syllabus

 

Representations, examples, G-modules and Maschke's theorem, Schur's lemma.

Character theory:  inner products, decompositions of the group algebra, orthogonality relations.

Calculation of character tables using commutator subgroup, inflation and induction.

Application in quantum chemistry.
