A fixed point theorem for closed-graphed decomposable-valued correspondences
Idione Meneghel, Rabee Tourky · arXiv (Cornell University) · 2013
We prove a fixed point theorem for closed-graphed, decomposable-valued correspondences whose domain and range is a decomposable set of functions from an atomless measure space to a topological space. One consequence is an improvement of the fixed point theorem in Cellina, Colombo, and Fonda (1986).
