FUNCTION: O2s - from the orthogonal Schur basis to the Schur basis

CALLING SEQUENCE:

O2s(sf)

CG[O2s](sf)

PARAMETERS:

sf = any element in the orthogonal Schur basis

SYNOPSIS:

• The O2s function converts any element expressed in the orthogonal Schur basis into an element expressed in the basis of Schur functions.

• The result is a linear combination of Schur functions.

• Whenever there is a conflict between the function name O2s and another name used in the same session, use the long form CG['O2s'].

EXAMPLES:

> with(CG):
> O2s(q*O[2,1] - O[1,1,1]);
 
                        q s[2, 1] - q s[1] - s[1, 1, 1]
