Abstract

In this paper, we study some results of existence and uniqueness of fixed points for a class of mappings satisfying an inequality of rational expressions. Our main result extends and unifies the well-known results of Khan [M. S. Khan, Rend. Inst. Math. Univ. Trieste, 8 (1976), 69–72]. c 2017 all rights reserved.
