Kostka-Foulkes polynomial for two given partitions.
KostaFoulkesPolynomial(lambda, mu)
The Kostka-Foulkes polynomial associated to lambda
and
mu
. This is a univariate qspray
polynomial whose value
at 1
is the Kostka number associated to lambda
and
mu
.
integer partitions; in order for the Kostka-Foulkes
polynomial to be non-zero, a necessary condition is that lambda
and mu
have the same weight; more precisely, mu
must
be dominated by lambda
