Some critical remarks on recent results concerning F-contractions in b-metric spaces

This paper aims to correct recent results on a generalized class of F-contractions in the context of b-metric spaces. The significant work consists of repairing some novel results involving F-contraction within the structure of b-metric spaces. Our objective is to take advantage of the property (F1) instead of the four properties viz. (F1), (F2), (F3) and (F4) applied in the results of Nazam et al. ["Coincidence and common fixed point theorems for four mappings satisfying (a(s), F)-contraction", Nonlinear Anal: Model. Control., vol. 23, no. 5, pp. 664-690, 2018]. Our approach of proving the results uti-lizing only the condition (F1) enriches, improves, and condenses the proofs of a multitude of results in the ex-isting state-of-art.
