Fixed point theorems for decomposable multi-valued maps and applications

3 years ago

Abstract

We present fixed point theorems for weakly sequentially upper semicontinuous decomposable non-convex-valued maps.They are based on an extension of the Arino-Gautier-Penot Fixed Point Theorem for weakly sequentially upper semicontinuous maps with convex values. Applications are given to abstract operator inclusions in $L_p$ spaces. An example is included to illustrate the theory.
