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.
WebSep 12, 2024 · Let F be a nonempty convex set of functions on a discrete group with values in [ 0, 1]. Suppose F is invariant with respect to left shifts and closed with respect to the pointwise convergence. Then F contains a constant function. This statement looks like Ryll-Nardzewski fixed point theorem, but it does not seem to follow from the theorem.
