Torsion in Graph Homology
Laure Helme-Guizon, Jozef H. Przytycki, Yongwu Rong
Khovanov homology for knots has generated a flurry of activity in the topology community. This paper studies the Khovanov type cohomology for graphs with a special attention to tor…

Graph Cohomologies from Arbitrary Algebras
Laure Helme-Guizon, Yongwu Rong
For each commutative, graded algebra with finite dimension in each degree, we construct a graded cohomology theory for graphs whose graded Euler characteristic is the chromatic pol…

Approximating Jones coefficients and other link invariants by Vassiliev invariants
Ilya Kofman, Yongwu Rong
We find approximations by Vassiliev invariants for the coefficients of the Jones polynomial and all specializations of the HOMFLY and Kauffman polynomials. Consequently, we obtain…
