Orbit space of group action

WebDefinition 2.5.1. Group action, orbit, stabilizer. Let G be a group and let X be a set. An action of the group G on the set X is a group homomorphism. ϕ: G → Perm ( X). 🔗. We say that the group G acts on the set , X, and we call X a G -space. For g ∈ G and , x ∈ X, we write g x to denote . ( ϕ ( g)) ( x). 1 We write Orb ( x) to ... WebApr 1, 2024 · Here, the orbit space is a manifold. This is usually not the case if the action of the group is not free, e.g. if the set $ X ^ {G} $ of fixed points is non-empty. A free action of a group is an action for which $ g=e $ follows if $ gx=x $ for any $ x \in X $.
