Web2 days ago · Introduction. Let X be a space admitting a continuous action of a topological group G.A typical problem associated to the pair (X; G) is to determine under what conditions the given action is free. Recall that, the action is called free if for any point x ∈ X the isotropy subgroup G x = {g ∈ G; g ⋅ x = x} is the trivial subgroup.. If G is a compact Lie … WebApr 11, 2024 · In this paper, the authors systematically discuss orbit braids in M × I with regards to orbit configuration space F G (M, n), where M is a connected topological manifold of dimension at least 2 with an effective action of a finite group G.These orbit braids form a group, named orbit braid group, which enriches the theory of ordinary braids.

A group action is faithful if the map G → Perm(X) has a trivial kernel. Checkpoint 2.5.2. Checkpoint 2.5.3. Proposition 2.5.4: Orbits of a group action form a partition Let group G act on set X. The collection of orbits is a partition of X.
WebGiven a topological spaceand a groupactingon it, the images of a single point under the group action form an orbitof the action. A fundamental domainor fundamental regionis a subset of the space which contains exactly one point from each of these orbits. It serves as a geometric realization for the abstract set of representatives of the orbits.
