Abstract: Complex K-theory is classified by the space of Fredholm operators, by

the Atiyah-Jänich theorem. It is known that one can up to homotopy pass

to a more structured space of operators, known as the restricted general

linear group. This is an infinite dimensional manifold with a Lie group

structure, for which the universal Chern character classes can be

represented as invariant differential forms. I will show that one can

also make this transition in the equivariant setting and obtain explicit

differential form representatives for the equivariant Chern character in

a suitable equivariant cohomology theory.
