Rectangular diagrams of surfaces: the basic moves

Ivan Dynnikov, Maxim Prasolov

英文摘要:

In earlier papers we introduced a representation of isotopy classes of compact surfaces embedded in the three-sphere by so called rectangular diagrams. The formalism proved useful for comparing Legendrian knots. The aim of this paper is to prove a Reidemeister type theorem for rectangular diagrams of surfaces.
