tSkewSchurPol function

Skew t-Schur polynomial

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

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)

Returns

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.
