A categorification for the Tutte polynomial

Edna F Jasso-Hernandez and Yongwu Rong

Algebraic & Geometric Topology 6 (2006) 2031–2049

arXiv: math.CO/0512613

Abstract

For each graph, we construct a bigraded chain complex whose graded Euler characteristic is a version of the Tutte polynomial. This work is motivated by earlier work of Khovanov, Helme-Guizon and Rong, and others.
