One of the most fundamental fixed-point theorems is Banach's Contraction Principle, of which the following conjecture is a generalization. Generalized Banach Contraction Conjecture (GBCC). Let be a self-map of a complete metric space , and let . Let be a positive integer. Assume that for each pair , . Then has a fixed point. Unlike Banach's original theorem (the case ), the above hypothesis does not compel to be continuous. In this paper we use Ramsey's Theorem from combinatorics to establish the GBCC for arbitrary in the case when is assumed to be continuous, and also derive a result which enables us to prove the GBCC when without the assumption of continuity; it is known that the case includes instances where is not continuous. |
