Graded multiplicities in the exterior algebra

Yuri Bazlov

Published 2000-12-23Version 1

We know the multiplicity of the adjoint representation of a semisimple Lie algebra in its own exterior algebra, but how do its copies distribute themselves between the exterior powers? The answer (the graded multiplicity) is obtained with the aid of Macdonald polynomials.
