Title: An Upper Bound on Reidemeister Moves

Abstract: given any two diagrams of the same knot or
link, we provide an explicit upper bound on the number
of Reidemeister moves required to pass between them in
terms of the number of crossings in each diagram. This
provides a new and conceptually simple solution to the
equivalence problem for knot and links. This is joint
work with Marc Lackenby.
