WebIn general, not all covering maps p will be the quotient by the action of a group: this will only be the case for normal covering maps, i.e. those for which p∗(π1(X˜)) is a normal subgroup N; Then π1(X, x0)/N is a group, and this will act in the same way as above, with quotient X. Example 1.39 (Coverings of surfaces). Web2. A covering is normal or regular or Galois if the group of deck transformations act transitively on the fibers. It's called "normal" because this is the case if and only if the …

WebThen the induced map q∗: QΓ(H) → QΓ(G) is a surjective, normal covering map with structure group (π1(G)/π1(H))r, and restricts to a nor-mal covering map q∗: XΓ(H) → XΓ(G) (with the same structure group). This result is proven in Section 3. We then discuss applications of this theorem Web4.

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. income tax telephone number ukWebThe space X has a universal covering space action G × Y → Y where G = π 1(X,x) is the fundamental group and Y is the universal covering space.
