If we regard a multi-valued mapping as a generalization of a singlevalued mapping, we may ask for generalizations of important properties as well, concerning zeros, fixed points, projection, composition etc. The main interest in this paper are continuity notions for multi-valued mappings which allow disconnected images, but still have a certain zero property. The starting point is a continuity ...

We apply Preuss' concept of $mbbe$-connectedness to the categories of lattice-valued uniform convergence spaces and of lattice-valued uniform spaces. A space is uniformly $mbbe$-connected if the only uniformly continuous mappings from the space to a space in the class $mbbe$ are the constant mappings. We develop the basic theory for $mbbe$-connected sets, including the product theorem. Furtherm...

Smarandache initiated neutrosophic sets (NSs) which can be used as a mathematical tool for dealing with indeterminate and inconsistent information. In order to apply NSs conveniently, single valued neutrosophic sets (SVNSs) were proposed by Wang et al. In this paper, we propose single valued neutrosophic relations (SVNRs) and study their properties. The notions of anti-reflexive kernel, symmetr...

this paper introduces an implicit scheme for a   continuous representation of nonexpansive mappings on a closed convex subset of a hilbert space with respect to a   sequence of invariant means defined on an appropriate space of bounded, continuous real valued functions of the semigroup.   the main result is to    prove the strong convergence of the proposed implicit scheme to the unique solutio...

We prove ?-convergence and strong convergence theorems of an iterative sequence generated by the Ishikawa’s method to a fixed point single-valued quasi-nonexpansive mappings in p-uniformly convex metric spaces without assuming convexity assumption. As consequence our version, we obtain result for multi-valued showing that every mapping taking compact values admits selection whose fixed-point se...

One of the tools for building new fixed-point results is use symmetry in distance functions. The symmetric property metrics particularly useful constructing contractive inequalities analyzing different models practical consequences. A lot important invariant point crisp mappings have been improved by using metrics. However, more than a handful theorems spaces are yet to be investigated fuzzy ve...

The concept of the lower limit for vector-valued mappings is the main focus of this work. We first introduce a new definition of adequate lower and upper level sets for vector-valued mappings and establish some of their topological and geometrical properties. Characterization of semicontinuity for vector-valued mappings is thereafter presented. Then, we define the concept of vector lower limit,...

In this paper, the concept of set-valued contraction of Nadler type in the setting of tvscone spaceswas introduced and a fixed point theorem in the setting of tvs-cone spaceswith respect to a solid conewas proved. Obtained results extend and generalize themain results of [S.B. Nadler Jr., Multi-valued contraction mappings, Pacific Journal of Mathematics 30 (1969) 475–488] and [D. Wardowski, On ...
