杰克多项式与自由累积量

Jack polynomials and free cumulants

Michel Lassalle

摘要:

本文研究了杰克多项式的幂和展开式中的系数。我们将它们表示为各向异性杨氏图的过渡测度的自由累积量中的多项式。我们猜想这类多项式具有非负整数系数。这推广了最近关于对称群的正规特征标的结果.

英文摘要:

We study the coefficients in the expansion of Jack polynomials in terms of power sums. We express them as polynomials in the free cumulants of the transition measure of an anisotropic Young diagram. We conjecture that such polynomials have nonnegative integer coefficients. This extends recent results about normalized characters of the symmetric group.
