Fixed point theorems for cyclic non-self single-valued almost contractions

Description

Let X be a Banach space, A and B two non-empty closed subsets of X and let T:A\cup B\to X be an operator. We define the notion of cyclic non-self almost contraction and we give a corresponding fixed point theorem.
