Normal covering map
WebFor example, there can be no global diffeomorphism from the 2-sphere to Euclidean 2-space although they do indeed have the same local differentiable structure. ... A smooth covering map is a local diffeomorphism such that every point in the target has a neighborhood that is evenly covered by the map.

Web4 G-sets, G-spaces and Covering Spaces Theorem 13 Assume that X is path-connected and locally path-connected. Then any π-map F 1 → F 2 extends uniquely to a map f:X˜ 1 → X˜ 2 of covering spaces over X. Proof As X˜ 1 is a covering space of X, it too is locally path-connected, and its path components are therefore open. Webprove Theorem 1.5 by showing that competed normal coverings are orbit maps if and only if they are discrete maps. In Section 4.2 we prove The-orem 1.6. In Section 4.3 we prove Theorems 1.7 and 1.9 by showing that a completed normal covering onto a PL manifold is discrete if and only if

Web26 de jan. de 2024 · A topological covering p: X ~ → X is normal when the group of deck transformations acts transitively on the fibers of p. This is equivalent to the fact that p ∗ ( π ( X ~, x ~)) is a normal subgroup of π ( X, p ( x ~)). Such coverings are also known as Galois or regular.
