Some applications of fixed point results for generalized two classes of Boyd–Wong’s F-contraction in partial b-metric spaces

摘要

In this paper, we will present some fixed point results for two classes of generalized contractions of Boyd–Wong type in partial b -metric spaces. More precisely, the structure of the paper is the following. In section one, we present some useful notions and results. The aim of section two is to introduce the concepts of Boyd–Wong F -contractions of type A and of type B and establish some new common fixed point results in partial b -metric spaces. We show the validity and superiority of our main results by suitable examples which are visualized by corresponding surfaces and related graphs. In section three, we correct some slip-ups in some recent papers. Finally, in section four, two applications to integral equation and periodic boundary value problem are included which make effective the new concepts and results.
