报告题目：Convolution formulas for multivariate arithmetic Tutte polynomials
报告摘要：The multivariate arithmetic Tutte polynomial of arithmetic matroid is a generalization of the multivariate Tutte polynomial of matroid. In this talk, we will give the convolution formulas for the multivariate arithmetic Tutte polynomial of the product of two arithmetic matroids. In particular,the convolution formulas for the multivariate arithmetic Tutte polynomialof an arithmetic matroid are obtained. Applying our results,severalknown convolution formulas are proved by a purely combinatorialproof. The proofs presented here are significantly shorter than the previous ones.In addition, we obtain a convolution formula for the characteristic polynomial of an arithmetic matroid. This is a joint work with Xian'an Jin and Weiling Yang.
