Regular homotopic deformation of compact surface with boundary and mapping class group

Geometric Topology 2009-04-03 v1

Abstract

A necessary and sufficient algebraic condition for a diffeomorphism over a surface embedded in the 3-sphere to be induced by a regular homotopic deformation is discussed, and a formula for the number of signed pass moves needed for this regular homotopy is given.
