SkewSchurPol: Skew Schur polynomial

In jack: Jack, Zonal, Schur, and Other Symmetric Polynomials

Skew Schur polynomial

Description

Returns the skew Schur polynomial.

Usage

SkewSchurPol(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)

Details

The computation is performed with the help of the Littlewood-Richardson rule (see LRskew).

Value

A qspray multivariate polynomial, the skew Schur polynomial associated to the skew partition defined by lambda and mu.

Examples

SkewSchurPol(3, lambda = c(3, 2, 1), mu = c(1, 1))
