5. ON THE PROBABILISTIC HAUSDORFF DISTANCE AND FIXED POINT THEOREMS FOR MULTIVALUED CONTRACTIONS DO HONG TAN PDF

   ▸ Abstract

   As is known, the Hausdorff distance plays an important role in fixed point theory for multivalued mappings. The aim of this note is to establish a relationship between the probabilistic Hausdorff distance and the usual one, and some fixed point theorems for multivalued contractions in Menger spaces.
