Abstract:
Let be a metric space, and be a continuous map. In this paper we prove that if is compact, and for all , then is equicontinuous if and only if there exist a pointwise recurrent isometric homeomorphism and a non-expanding map that is pointwise convergent to a fixed point such that is uniformly conjugate to a subsystem of the product map . In addition, we give some still simpler necessary and sufficient conditions of equicontinuous graph maps.
