Heisenberg group acts on the circle
@MatthiasWendt In fact, I want to prove such $c$ is trivial, so the first step is to prove the fixed points of $c$ is finite under the hypothesis, then there would be a contradictory. Thanks for the reference, but it doesn't show the set of fixed point of $c$ is finite.

@MatthiasWendt We suppose the action of $c$ is non trivial.
