Module aims

The aims of the module are to: introduce the notion of an algebraic group as a group which also carries the structure of an affine variety; to study particular algebraic groups such as special linear groups, also solvable algebraic groups, connected algebraic groups and tori; to develop some of the general properties of these groups via a small amount of representation theory.

Module learning outcomes

  • The concept of an algebraic group as a group and an affine variety or algebraic set in affine space.

  • How the group operations viewed as homomorphisms of algebraic sets influence the group structure of an algebraic group.

  • Common examples of groups, such as general linear groups, special linear groups and groups of upper triangular matrices in the context of algebraic group theory.

  • The notion of the connected component of an algebraic group and be able to compute it in simple examples.

  • Diagonalisable groups.

Module content
