Khovanov's conjecture over Z[c]

Geometric Topology 2007-05-23 v1 Quantum Algebra

Abstract

We disprove the conjecture of M. Khovanov (math.QA/9908171) on the functoriality of his link homology with polynomial coefficients. This is in contrast to the case of integer coefficients, where functoriality was proved in math.GT/0206303 .
