WebX is canonical and further that the group G lies in an extremely narrow class. Roughly speaking, our method is to try to lift the action of euclidean n-space up to the total space of the bundle and observe what obstructs this effort. The torus of dimension k will be denoted by Tk, the corresponding euclidean space by Rk. We view Rk as acting transitively on Tk … 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 $.
