Best Proximity Point Results in b-Metric Space and Application to Nonlinear Fractional Differential Equation

Abstract: Brinde [Approximating fixed points of weak contractions using the Picard itration, Nonlinear Anal. Forum 9 (2004), 43-53] introduced almost contraction mappings and proved Banach contraction principle for such mappings. The aim of this paper is to introduce the notion of multivalued almost Θcontraction mappings and present some best proximity point results for this new class of mappings. As applications, best proximity point and fixed point results for weak single valued Θ-contraction mappings are obtained. An… Show more

“…The geometrical property, that is, the proximal normal structure, is the sufficient condition for the existence of the best proximity [1]. For details about the best proximity point, one can see research papers in [1,2,5,[15][16][17][18][19]. We now prove the following result, which shows that the above condition can be dropped if a reflexive Banach space satisfies Opial's condition.…”

“…Whereas a cyclic mapping does not necessarily have a fixed point, it is desirable to determine an element x which is somehow closest to Tx: More precisely, an element x for which the error dðx, TxÞ assumes the least possible value distðA, BÞ where distðA, BÞ = inf fdðx, yÞ: x ∈ A, y ∈ Bg, such a point is called a best proximity point of the cyclic mapping T: Since 2003, research on best proximity points of cyclic mapping became an important topic in nonlinear analysis and has been studied by many authors [2][3][4][5][6][7][8].…”

“…Later in [2], the class of C * -algebra valued b-metric spaces is considered. Many results are introduced in this direction (see [3][4][5][6][7][8][9][10]). e notion of α-ψ-contractive mappings in metric spaces was introduced by Samet et al [11].…”
