In this paper, we define almost Rg-Geraghty type contractions and utilize the same to establish some coincidence common fixed point results in setting of b2-metric spaces endowed with binary relations. As consequences our newly proved results, deduce for g-?-? Geraghty contraction mappings spaces. addition, derive partially ordered Moreover, show utility main provide an example application non-...

We study the question of whether or not contractive representations of logmodular algebras are completely contractive. We prove that a 2-contractive representation of a logmodular algebra extends to a positive map on the enveloping C∗-algebra, which we show generalizes a result of Foias and Suciu on uniform logmodular algebras. Our proof uses non-commutative operator space generalizations of cl...

in the present paper, we introduces the notion of integral type contractive mapping with respect to ordered s-metric space and prove some coupled common fixed point results of integral type contractive mapping in ordered s-metric space. moreover, we give an example to support our main result.

in this paper,  we provide two different kinds of fixed pointtheorems in  fuzzy metric spaces. the first kind is for the fuzzy$varepsilon$-contractive type mappings and  the second kind is forthe fuzzy order $psi$-contractive type mappings. they improve thecorresponding  conclusions in the literature.

In the framework of metric spaces, we introduce concept Geraghty-Ciric type contractions and show existence uniqueness fixed point such mappings. This result improves unifies those obtained by Geraghty (Proc. Amer. Math. Soc. 40, 604-608 (1973)) Ciric 45, 267-273, (1974)). Several technical lemmas are employed to ensure that a Picard sequence is Cauchy sequence. addition, two illustrative examp...
