flaggedSchurPol {jack}

Flagged Schur polynomial

Description

Computes a flagged Schur polynomial (which is not symmetric in general). See Chains in the Bruhat order for the definition.

Usage

flaggedSchurPol(lambda, a, b)

Arguments

lambda

integer partition

a, b

lower bounds and upper bounds, weakly increasing vectors of integers; lambda, a and b must have the same length

Value

A qspray polynomial.

Examples

lambda <- c(3, 2, 2)
n <- 3
a <- c(1, 1, 1); b <- c(n, n, n)
flaggedPoly <- flaggedSchurPol(lambda, a, b)
poly <- SchurPol(n, lambda)
flaggedPoly == poly # should be TRUE
