报告摘要:  Goulden and Jackson conjectured, and Greene later proved, that immanants of Jacobi-Trudi matrices are polynomials with nonnegative integer coefficients. This led Stembridge and Stanley to formulate a series of immanant conjectures, including the well known (3+1)-free conjecture. In this talk we shall give an overview of Goulden and Jackson's conjecture and related results, and report some of our results on the character immanants of combinatorial matrices. This talk is based on the joint work with Ethan Li, Grace Li and Candice Zhang.
