SkewMacdonaldPol: Skew Macdonald polynomial

Description

Returns the skew Macdonald polynomial associated to the given skew partition.

Usage

SkewMacdonaldPol(n, lambda, mu, which = "P")

Value

A symbolicQspray multivariate polynomial, the skew Macdonald polynomial associated to the skew partition defined by

lambda and mu. It has two parameters usually denoted by q and t. Substituting q with 0

yields the skew Hall-Littlewood polynomials.

Arguments

n

number of variables, a positive integer

lambda, mu

integer partitions defining the skew partition: lambda is the outer partition and mu is the inner partition (so mu must be a subpartition of lambda)

which

which skew Macdonald polynomial, "P", "Q" or "J"
