A Unique Common Coupled Fixed Point Theorem for Four Maps in Partial b-Metric-Like Spaces

Abstract

We prove the existence of a unique common coupled fixed point theorem for four mappings satisfying a general contractive condition on partial b-metric-like spaces. We also give an example to illustrate our main theorem. Our theorem generalizes and improves the theorem of [1].
