tSchurPol function

t-Schur polynomial

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

tSchurPol(n, lambda)

Arguments

• n: number of variables, a positive integer
• lambda: integer partition

Returns

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

Note

The name "t-Schur polynomial" is taken from Wheeler and Zinn-Justin's paper

Hall polynomials, inverse Kostka polynomials and puzzles.
