Abstract
This paper is aimed at studying the uniqueness of coincidence best proximity point forϑ,α+,g-proximal contractions in complete Branciari metric space. Throughout this article, discontinuity of the Branciari metric space is used and we obtained the desired results without assuming it as a continuous. Some examples are provided to validate the results proved herein. As an application, we derive the best proximity point results in the setup of complete Branciari metric space endowed with graph. Further, our results extend and generalize the existing ones in literature.

Summary
Introduction and PreliminariesLet F : X ⟶ X be a mapping, where X be any nonempty set. “An element q∗ ∈ X is a fixed point of F if q∗ satisfies the equation Fq∗ = q∗ (known as a fixed point equation) or dðq∗, Fq∗Þ = 0:} A collection of all “fixed points” of F will be represented as FðXÞ, that is, FðXÞ = fq∗ ∈ X : dðq∗, Fq∗Þ = 0g: ð1Þ In this direction, Banach [1] gives the existence and uniqueness of the “fixed point” of the self mapping F, if mapping F is a contraction and ðX, dÞ is a complete, but it becomes more interesting, if F is a nonself mapping it is not necessary that the operator equation Fq∗ = q∗ has a solution. Several authors studied the results dealing with “approximate fixed points” in different spaces (for detail, see [3,4,5,6,7,8,9,10,11,12,13,14])
