报告摘要  Abstract

Using Alexander modules, one can define a polynomial invariant for a certain class of graphs with a balanced coloring. We will give different interpretations of this polynomial by Kauffman state formula and MOY relations.  Moreover, we propose a potential categorification for the invariant.
