In this paper, we prove two theorems about fixed point and coupled coincidence point in generalized -metric space via Ï-distance for a mapping satisfying a contraction condition.

In this paper we present some coupled coincidence and coupled common fixed point theorems for mixed G-monotone mappings in partially ordered G-metric spaces.

In this paper we present some coupled coincidence and coupled common fixed point theorems for mixed G-monotone mappings in partially ordered G-metric spaces.

In this paper, our main goal is to present a non-classical MPFA method coupled with a high order finite volume method for the simulation of oil water displacements in heterogeneous and anisotropic petroleum reservoirs using general polygonal meshes. The g... see more

We study theoretical models of three coupled wave guides with a PT-symmetric distribution of gain and loss. A realistic matrix model is developed in terms of a three-mode expansion. By comparing with a previously postulated matrix model it is shown how pa... see more

In this paper, by using the concept of belongingness (?) and quasi-coincidence (q) between fuzzy points and fuzzy sets, we introduce (a, ß)-fuzzy positive implicative ideals in BCK-algebras where a, ß are any of {?, q, ? V q, ? ^ q} with a ? ? ^ q.  

The paper presents the work possibilities in exploitation of the suspension mechanism of classic type with coupling machines in 3 points . The researches were related to the following aspects: the heights of coupling points of tyrants at Roman... see more

Exceptional points (EPs) determine the dynamics of open quantum systems and cause also PT symmetry breaking in PT symmetric systems. From a mathematical point of view, this is caused by the fact that the phases of the wavefunctions (eigenfunctions of a no... see more

Wind-induced vegetation patterns were proposed a long time ago but only recently a dynamic vegetation-sand relationship has been established. In this research, we transformed the continuous vegetation-sand model into a discrete model. Fixed points and sta... see more
