sage: lmbda = Partition([3,2,1]) sage: mu = Partition([1]) sage: s = SymmetricFunctions(QQ).s(); s Symmetric Function Algebra over Rational Field, Schur symmetric functions as basis sage: s(lmbda/mu) s[2, 2, 1] + s[3, 1, 1] + s[3, 2] sage: s([[3,2,1],[1]]) s[2, 2, 1] + s[3, 1, 1] + s[3, 2] --Mike -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
