摘要：The multiplicity Tutte polynomial including the arithmetic Tutte polynomial is a generalization of classical Tutte polynomial of matroids. In this talk, we will present the expressions of extreme coefficients of multiplicity Tutte polynomials, and then the expressions of extreme coefficients of arithmetic Tutte polynomials are obtained. In particular, as corollaries, the expressions of extreme coefficients of Tutte polynomial for matroids are deduced. This is a joint work with Xian’an Jin and Weiling Yang.
