Let Y be an absolute neighbourhood retract (ANR) for the class of metric spaces and let X be a topological space.Let YX denote the space icon track bar f250 of continuous maps from X to Y equipped with the compact open topology.We show that if X is a compactly generated Tychonoff space and Y is not discrete, then YX is an ANR for metric spaces if and only if turbosound ts-18sw700/8a X is hemicompact and YX has the homotopy type of a CW complex.
