On the Markov theorem for free links
Abstract: The theory of free knots/links invented by V. O. Manturov is a
simplification of virtual knots theory and is useful in the study of
various knots invariants. The Markov theorem gives precisely the condition
when two braids have isotopic closure. We will present a Markov theorem of
free links (http://arxiv.org/abs/1112.4061). This joint work with V. O.
Manturov is proved using the L-move method introduced by Kauffman and
Lambropoulou in "virtual braids and the L-move" in 2006.
