This paper is an introduction to the theory of virtual knots. It is dedicated to the memory of Francois Jaeger.
State Models and the Jones Polynomial
IN THIS PAPER I construct a state model for the (original) Jones polynomial [5]. (In [6] a state model was constructed for the Conway polynomial.) As we shall see, this model for the Jones polynomial

An invariant of regular isotopy
This paper studies a two-variable Laurent polynomial invariant of regular isotopy for classical unoriented knots and links. This invariant is denoted LK for a link K, and it satisfies the axioms: 1.
An Introduction to Knot Theory
This paper concentrates on the construction of invariants of knots, such as the Jones polynomials and the Vassiliev invariants, and the relationships of these invariants to other mathematics (such as

TLDR
A generalization of the Tutte polynomial that is defined for signed graphs to provide a link between knot theory and graph theory, and to explore a context embracing both subjects.
Signature of links
Let L be an oriented tame link in the three sphere S3. We study the Murasugi signature, a(L), and the nullity, r(L). It is shown that a(L) is a locally flat topological concordance invariant and that
