Aims
To introduce the basic ideas of studying groups through their representations as matrices, and to describe finite dimensional complex representations of finite groups.
Module Summary
The module presents the theory of finite dimensional complex representations of finite groups including the discussion of important classes of examples. Starting from the motivating question how a group can act linearly on a vector space, students will see an instance of a complete mathematical theory. While of major importance for the study of finite groups, this setup also forms a starting point for more general representation theory.
Outline Of Syllabus
Review of group theory, general linear group. Review of linear algebra. (Complex) representations of groups (subrepresentations, morphisms of representations). Maschke’s Theorem. Schur’s Lemma. Characters and orthogonality relations. Regular representation. Projection formulas. Representations of the symmetric group.

Teaching Rationale And Relationship
Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the students’ abilities at applying the theory to solving problems.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.
Note: the exam for MAS8709 is more challenging than the exam for MAS3709
