Using the homeomorphism between the projective line and the sphere , we can draw the action as in Figure 1. Figure 1. The -action on , pictured as the sphere . The action flows from the north to the south pole. This is an example of Białynicki-Birula decomposition. There are some similarities with Morse theory.
