WebbNow, since S2n is simply connected, we have p 1(X)˘=G; and thus p 1(X) is either trivial or Z=2Z. (c)If S2n+1 covers X, then every nontrivial deck transformation has degree ( 1)2n+2 = 1. By the Hopf degree theorem, every deck transformation is homotopic to the identity. In particular every deck transformation is locally orientation-preserving.

A closely related notion uses the idea of covering space. For a connected manifold M take M , the set of pairs (x, o) where x is a point of M and o is an orientation at x; here we assume M is either smooth so we can choose an orientation on the tangent space at a point or we use singular homology to define orientation. Then for every open, oriented subset of M we consider the corresponding set of pairs and define that to be an open set of M . This gives M a topology and t… WebbA dualistic structure on a smooth Riemaniann manifold M is a triple (M,g,∇) with g a Riemaniann metric and ∇ an affine connection generally assumed to be torsionless. From g and ∇, dual connection ∇* can be defined. In this work, we give conditions on the basis of this notion for a manifold to admit an almost contact structure and some related …
