WebThe group G(S) is always nite, and we shall say a little more about it later. 7. The remaining two examples are more directly connected with group theory. If Gis a group, then Gacts on itself by left multiplication: gx= gx. The axioms of a group action just become the fact that multiplication in Gis associative (g 1(g 2x) = (g 1g 2)x) and the ... WebAug 28, 2024 · The action of G on P preserves T and descends to the quotient space F = T / ∼. It is easy to check that every G -orbit in F is discrete, closed, but the map F → F / G is not a covering map (say, at the equivalence class of (0,1)). In this example, F is homeomorphic to the open Moebius band.
