Web3 de abr. de 2024 · I tried to find the criterion for a covering map to be normal. However, the criterion I came up with and proved seems to be a little bit weaker than what is stated in other textbooks. I don't know ...

Local homeomorphism Since a covering $${\displaystyle \pi :E\rightarrow X}$$ maps each of the disjoint open sets of $${\displaystyle \pi ^{-1}(U)}$$ homeomorphically onto $${\displaystyle U}$$ it is a local homeomorphism, i.e. $${\displaystyle \pi }$$ is a continuous map and for every $${\displaystyle e\in E}$$ there … Ver mais A covering of a topological space $${\displaystyle X}$$ is a continuous map $${\displaystyle \pi :E\rightarrow X}$$ with special properties. Ver mais • For every topological space $${\displaystyle X}$$ there exists the covering $${\displaystyle \pi :X\rightarrow X}$$ Ver mais Definition Let $${\displaystyle p:{\tilde {X}}\rightarrow X}$$ be a simply connected covering. If commutes. Ver mais Definition Let $${\displaystyle p:E\rightarrow X}$$ be a covering. A deck transformation is a homeomorphism $${\displaystyle d:E\rightarrow E}$$, … Ver mais Let $${\displaystyle X}$$ be a connected and locally simply connected space, then for every subgroup $${\displaystyle H\subseteq \pi _{1}(X)}$$ there exists a path-connected covering $${\displaystyle \alpha :X_{H}\rightarrow X}$$ with Let Ver mais Definitions Holomorphic maps between Riemann surfaces Let $${\displaystyle X}$$ and $${\displaystyle Y}$$ be Riemann surfaces, i.e. one dimensional complex manifolds, and let Ver mais Let G be a discrete group acting on the topological space X. This means that each element g of G is associated to a homeomorphism Hg of X onto itself, in such a way that Hg h is always equal to Hg ∘ Hh for any two elements g and h of G.

WebWhen covering spaces are involved in any way, try computing Euler characteristics - this sometimes yields nice numerical constraints. For p: A → B an n- fold cover, χ(A) = nχ(B). Covering spaces of orientable manifolds are orientable. The preimage of a boundary point under a covering map must also be a boundary point.
