QUADRUPLE FIXED POINT THEOREMS FOR (α,ψ) - CONTRACTIVE TYPE MAPPINGS IN PARTIALLY ORDERED METRIC SPACES
Main Article Content
Abstract
In this paper, we determine some quadruple fixed point theorems for nonlinear contractive mappings in the framework of a metric space enclosed with partial order. We prove the uniqueness of a quadruple fixed point for such mappings in this setup. Also, we introduce some examples to illustrate the effectiveness of our results.
