In the proof that covering transformations are covering maps, why is $q\circ (p_2) _W$ a local inverse for $F$? Because I was using the lifting criterion, I should have added an assumption about my spaces in the first theorem. WebThe lifting of the first part is a path in X ~ from x ~ 0 to φ ~ ( y), and the lifting of the second second part is a path in p − 1 ( U ′) from φ ~ ( y) to φ ~ ( y ′).

We need to show that it is not a normal covering. We know that the fundamental group ˇ 1(K) has the presentation ˇ 1(K) ˘=ha;bjabab 1 = ei since K is built by attaching a 2-cell to the above depicted fundamental polygon.

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. 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. The universal covering is known to be always normal.

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.
