There is a strong analogy between continuous sections of a topological fibration, rational points of a variety defined over a nonclosed field, and fixed points of the action of a finite group. I will explain this analogy as well as a number of recent results for rational points and fixed points suggested by this analogy: a theorem of de JongHeStarr, Yi Zhu's theorem, the TianZong theorem, and workinprogress of Chenyang Xu and myself for rational points of varieties over global function fields.
