in this paper, we improve some recent coupled fixed point resultsfor single-valued operators in the framework of ordered $b$-metricspaces established by bota et al. [m-f. bota, a. petrusel, g.petrusel and b. samet, coupled fixed point theorems forsingle-valued operators in b-metric spaces, fixed point theoryappl. (2015) 2015:231]. also, we prove that perov-type fixed pointtheorem in ordered gen...

in this paper,  the concept of fuzzy metric-like spaces is introduced which generalizes  the notion of fuzzy metric spaces given by george and veeramani cite{vee1}. some fixed point results for fuzzy contractive mappings on fuzzy metric-like spaces are derived. these results generalize several comparable results from the current literature. we also provide illustrative examples in support of ou...

in this paper we define weak $f$-contractions on a‎ ‎metric space into itself by extending $f$-contractions‎ ‎introduced by d‎. ‎wardowski (2012) and provide some fixed point‎ ‎results in complete metric spaces and in partially ordered complete ‎generalized metric spaces‎. ‎some relationships between weak‎ ‎$f$-contractions and $fi$-contractions are highlighted‎. ‎we also ‎give some application...

We can see from (p) and (p) that p(x, y) =  implies x = y. However, the converse is not necessarily true. A typical example of this situation is provided by the partial metric space (R,pmax), where the function pmax : R+ × R+ → R+ is defined by pmax(x, y) =max{x, y} for all x, y ∈ R+. Other examples of partial metric spaces which are interesting from a computational point of view may be foun...

In this paper, we prove a general fixed point theorem in $textrm{S}$-metric spaces for maps satisfying an implicit relation on complete metric spaces. As applications, we get many analogues of fixed point theorems in metric spaces for $textrm{S}$-metric spaces.

the general relatively isotropic mean landsberg metrics contain the general relativelyisotropic landsberg metrics. a class of finsler metrics is given, in which the mentioned two conceptsare equivalent. in this paper, an interpretation of general relatively isotropic mean landsberg metrics isfound by using c-conformal transformations. some necessary conditions for a general relativelyisotropic ...

We consider a finite rig-etale morphism f: Y → X of quasi-smooth Berkovich curves over complete algebraically closed valued field extension k ℚp and skeleton Γf = (ΓY, ΓX) the f. prove that radializes f if only ΓX controls pushforward constant p-adic differential equation $${f_*}\left( {{{\cal O}_Y},{d_Y}} \right)$$ . Furthermore, when is open unit discs arbitrary characteristic, we radial num...
