A polynomial invariant of virtual knots

Geometric Topology 2012-02-20 v1

Abstract

The aim of this paper is to introduce a polynomial invariant fK(t)f_K(t) for virtual knots. We show that fK(t)f_K(t) can be used to distinguish some virtual knot from its inverse and mirror image. The behavior of fK(t)f_K(t) under connected sum is also given. Finally we discuss which kind of polynomial can be realized as fK(t)f_K(t) for some virtual knot KK.
