Lay Summary.
The set of symmetries of a geometric object (for example, the
rotations and reflections which leave it looking the same) form what
is called a group. The abstraction of this gives rise to the
notion of an abstract group, and representation theory
is concerned with the reverse process: trying to find suitable
geometric objects of which an abstract group can be regarded as
symmetries.
This project will look at the representation theory of so-called
classical groups of matrices whose entries come from a set of
"numbers" called a p-adic field. Parts of the representation
theory of these groups are governed by the algebra of certain
functions on them. We will compute this algebra, to understand, in
particular, a connection which should exist between the algebras for
symplectic and orthogonal groups.
