A fixed point theorem revisited

Author:

Bollenbacher Alberta,Hicks T. L.

Abstract

A version of a theorem commonly referred to as Caristi’s Theorem is given. It has an elementary constructive proof and it includes many generalizations of Banach’s fixed point theorem. Several examples illustrate the diversity that can occur.
