FUNCTION: CgSchurSeries - truncated Schur function series

CALLING SEQUENCE:

CgSchurSeries(typ, rank)

CG[CgSchurSeries](typ, rank)

PARAMETERS:

typ = the type of the Schur function series

rank = the rank of truncature

SYNOPSIS:

• The CgSchurSeries function computes the Schur function series of a given type truncated to the given rank. The available types are A, B, C and D, according to the notations of King and Wybourne.

• The result is a linear combination of Schur functions.

• Whenever there is a conflict between the function name CgSchurSeries and another name used in the same session, use the long form CG['CgSchurSeries'].
