A note on equicontinuous maps of graph space

1 Introduction 1 Let X as a compact metric space with the metric d and f :X → Xas a continuous map. For every nonnegative integer n , define f ninductively by f n = f ? f n?1, with f 0as the identity map on X . If there is a positive integer n such that f n( x )= x, the point x of X is called the periodic point of f and the least n is called the periodic point of x . A periodic point is called a fixed point. Denote the fixed points set and the periodic points set of f respectively by F ( f…
