MSPcombination {qspray}

Symmetric polynomial in terms of the monomial symmetric polynomials

Description

Expression of a symmetric polynomial as a linear combination of the monomial symmetric polynomials.

Usage

MSPcombination(qspray, check = TRUE)

Arguments

qspray

a qspray object defining a symmetric polynomial

check

Boolean, whether to check the symmetry

Value

A list defining the combination. Each element of this list is a list with two elements: coeff, a bigq number, and lambda, an integer partition; then this list corresponds to the term coeff * MSFpoly(n, lambda), where n is the number of variables in the symmetric polynomial.

Examples

qspray <- PSFpoly(4, c(3, 1)) + ESFpoly(4, c(2, 2)) + 4L
MSPcombination(qspray)
