Decomposition of the Diagonal Action of Sn on the
Coinvariant Space of Sn x Sn
The purpose of this paper is to give an explicit description of the
irreducible decomposition of the bigraded Sn-module of
coinvariants of Sn x Sn.
Many of the results presented
here can be extended to Snk,
and to other finite reflection
