tSkewSchurPol {jack}

Skew t-Schur polynomial

Description

Returns the skew t-Schur polynomial associated to the given skew partition.

Usage

tSkewSchurPol(n, lambda, mu)

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)

Value

A symbolicQspray multivariate polynomial, the skew t-Schur polynomial associated to the skew partition defined by lambda and mu. It has a single parameter usually denoted by t and its coefficients are polynomials in this parameter. Substituting t with 0 yields the skew Schur polynomials.
