The book is the first systematic research completely devoted to a
comprehensive study of virtual knots and classical knots as its
integral part. The book is self-contained and contains up-to-date
exposition of the key aspects of virtual (and classical) knot
theory.Virtual knots were discovered by Louis Kauffman in 1996.
When virtual knot theory arose, it became clear that classical knot
theory was a small integral part of a larger theory, and studying
properties of virtual knots helped one understand better some
aspects of classical knot theory and encouraged the study of
further problems. Virtual knot theory finds its applications in
classical knot theory. Virtual knot theory occupies an intermediate
position between the theory of knots in arbitrary three-manifold
and classical knot theory.In this book we present the latest
achievements in virtual knot theory including Khovanov homology
theory and parity theory due to V O Manturov and graph-link theory
due to both authors. By means of parity, one can construct
functorial mappings from knots to knots, filtrations on the space
of knots, refine many invariants and prove minimality of many
series of knot diagrams.Graph-links can be treated as "diagramless
knot theory": such "links" have crossings, but they do not have
arcs connecting these crossings. It turns out, however, that to
graph-links one can extend many methods of classical and virtual
knot theories, in particular, the Khovanov homology and the parity
theory.
