Fixed Points of Multivalued Contractions
P. V. Semenov Moscow City Pedagogical University, Mathematical Department
Abstract:
A fixed-point theorem is proved for a broad class of closed-valued $k(\;\cdot\;)$-contractions with $\limsup_{s\to t+0}k(s)<1$ for any positive $t$ and with $\limsup_{s\to0+0}k(s)=1$.
Keywords:
multivalued contraction, fixed point, Reich's problem, $G$-summable function.
