On Presic Type Generalization of the Banach Contraction Mapping Principle
L. Ciric and S. Presic


Abstract.  Let (X, d) be a metric space, k a positive integer and T a mapping of Xk into X. In this paper we proved that if T satisfies conditions (2.1) and (2.2) below, then there exists a unique x in X such that T(x, x,¼, x) = x, This result generalizes the corresponding theorems of the second author [4], [5] and the theorem of Dhage [3].

Keywords:  fixed point, Cauchy sequence, Complete metric space.
