For the problem to be well-posed, each entity must be specified by a finite description and it must be clear whether a putative description actually describes an e

Online Warenwirtschaftssysteme,mple of a 3-manifold which has trivial homology but is not homeomorphic to the 3-sphere, the fundamental group is a powerful if sometimes intractable invariant of a topological space. The aim of this essay is to describe the complex interaction between the algebra and the geometry that is transmitted through the medium of the fundamental group.
