Some New Results for Jaggi-W-Contraction-Type Mappings on b-Metric-like Spaces

In this article, we generalize, improve, unify and enrich some results for Jaggi-W-contraction-type mappings in the framework of b-metric-like spaces. Our supplement numerous methods existing literature, created new approach to prove that a Picard sequence is Cauchy space. Among other things, Wardowski’s theorem, but now by using only property (W1). proofs article are much shorter than ones recently published papers.
