... Let G be a locally compact topological group. Definition 2.2. A G-space is a locally compact topological space X, equipped with a G-action, i.e. a continuous map a : G × X → X satisfying a(e, x) = x and a(g1 , a(g2 , x)) = a(g1 g2 , x). We usually write simply gx instead of a(g, x). A morphism betwe ...
