WebMay 7, 2024 · Suppose X is a finite CW complex and X admits a fixed-point free action of G := Z / p Z for some prime p. Prove that p divides χ ( X). We can show this using the Lefschetz fixed point theorem. If σ ∈ G is a generator, then σ ⋆ on H k ( X, Q) satisfies σ ⋆ p = Id, so all its eigenvalues are p th roots of unity. WebDec 31, 2024 · Dec 31, 2024 at 12:42 1 A free action of G on X essentially means that X can be identified with a disjoint union of copies of G where G acts on each copy of itself by left-multiplication. Every (other) G -set can be viewed as a quotient (orbit-wise) of such a free G -set. – Hagen von Eitzen Dec 31, 2024 at 13:27 "What does "free" mean"?

Abstract - University at Albany, SUNY

Web(1) If a finite group acts transitively but not trivially on a set, then some element of the group has no fixed points. You can also use (0) to show: (2) When a nontrivial finite group acts on a set in such a way that every g ≠ 1 has exactly one fixed point, then apart from free orbits there must be exactly one orbit, of size 1. WebIt is straightforward that every coprime action is a good action. In this work, we extend some results due to Ward, Gross, Shumyatsky, Jabara and Meng and Guo under coprime action to good action.
