Abstract
Let be a (topological) space and the collection of nonempty closed subsets of . Given a topology on , making a space, a (subset) hyperspace of is a subspace with an embedding , . In this note, we characterize certain hyperspaces as explicit quotient spaces of function spaces and discuss metrization of associated compact-subset hyperspaces in this setting. In particular, we find that any hyperspace topology containing the Vietoris topology is a quotient of a function space topology containing the topology of pointwise convergence.
