Module summary
Multiplication by a complex number of absolute value one gives a rotation of the complex plane. In the 19th Century, Hamilton tried to find an algebra which would represent rotations of three-dimensional space. After much thought he realized that he had to give up commutativity and needed a four-dimensional algebra, his quaternions. Soon a beautiful theory had developed, with Grassmann and Clifford providing other examples of algebras (now used in quantum mechanics and relativity) and Wedderburn determining the structure of all 'semisimple' algebras. This module also includes an introduction to the notions of quivers and their representations, which provide a combinatorial language for the description of algebras with beautiful properties. As well as being of interest in its own right, this module should extend and consolidate the students' understanding of linear algebra.Objectives
On completion of this module, students should be able to:a) Define some of the main concepts about associative algebras and representations.
b) State and prove some of the basic results about associative algebras and representations.
c) Compute in various examples of algebras.
d) Compute bases for some examples of algebras given by generators and relations.
e) Use the isomorphism theorems to construct isomorphisms between modules
f) Determine whether or not an algebra is semisimple.
g) Determine whether or not a representation is indecomposable.
Syllabus
Associative algebras and examples. Division algebras. Algebras given by generators and relations. Modules and the Isomorphism Theorems. Simple and semisimple modules. Semisimple algebras. Representations of quivers.
