Daniele Ettore Otera, Valentin Poénaru and Corrado Tanasi: On Geometric Simple Connectivity, p.157-176

Abstract:

We will give a very quick panoramic view of some more or less recent research, mostly by the second author (V.P.), in the fields of low-dimensional topology and geometric group theory.

Key Words: Handles, GSC, 4-dimensional manifolds, quasi-simple filtration, double-points, presentations and (inverse)-representations of groups.
