Whitnet map for hyperspaces of continua with the property of Kelley

The main purpose of this paper is to study properties of continua with the property of Kelley which admit a Whitney map either for hyperspace C(X) or for C^2(X). In particular, it is proved that an arcwise connected continuum X with the property of Kelley admits a Whitney map for C(X) if and only if it is metrizable.
