Webb(1) If Mis even dimensional and orientable, then Mis simply connected. (2) If Mis odd dimensional, then Mis orientable. Before proving the theorem, we need two lemmas: Lemma 2.2. Let (M;g) be a compact Riemannian manifold. Then for any nontriv-ial free homotopy class C, there exists a closed geodesic whose length is minimal in C. Proof. … Webbwhen n ≥ 10 and a positively curved closed simply connected n-manifold M has symmetry rank at least n 4 + 1, M is homeomorphic to Sn or HPn4 or homotopy equivalent to CP n 2 in [Wil03].

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.

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.
