报告摘要：The interior polynomial and the exterior polynomial are generalizations of valuations on (x,1) and (1,y) of the Tutte polynomial T_G(x,y) of graphs to hypergraphs, respectively. The top of the HOMFLY polynomial of a special alternating link coincides with the interior polynomial of the pair of hypergraphs induced by the Seifert graph of the link.

In this talk, we will introduce these two polynomials, giving a detailed account of their definitions, their relations with the Tutte polynomial in graph theory and the HOMFLY polynomial in knot theory. Then we give a brief account of known results, our works on coefficients, tools and ideas used in the proofs, and so on. This is a joint work with Xiaxia Guan.
