New applications of the existence of solutions for equilibrium equations with Neumann type boundary condition

open access: yesJournal of Inequalities and Applications, 2017
Using the existence of solutions for equilibrium equations with a Neumann type boundary condition as developed by Shi and Liao (J. Inequal. Appl. 2015:363, 2015), we obtain the Riesz integral representation for continuous linear maps associated with ...

On the K-continuity of K-hull midconvex set-valued functions

open access: yesLe Matematiche, 1993
In the present paper it is proved the K-continuity of a set-valued function which is K-hull midconvex, K-lower semicontinuous at a point and whose values are bounded K-midconvex sets; the concept of K-hull midconvexity is introduced here and it is weaker

Second Hukuhara derivative and cosine family of linear set-valued functions

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2006
Let $K$ be a closed convex cone with the nonempty interior in a real Banach space and let $cc(K)$ denote the family of all nonempty convex compact subsets of $K$.

Minimal Partial Ultraclones on a Two-Element Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2014
Set of functions from a finite set A to set of all subsets of A is a natural generalization of the set of many-valued functions on A (k-valued logic functions).

Traditional continuum theory arising in inverse limits with set-valued functions

open access: yesRevista Integración, 2019
In the years since their introduction in 2004, almost 100 articles and books have been written on the subject of inverse limits with set-valued functions.

Existence of fixed points on compact epilipschitz sets without invariance conditions

open access: yesFixed Point Theory and Applications, 2005
We provide a new result of existence of equilibria of a single-valued Lipschitz function f on a compact set K of ℝn which is locally the epigraph of a Lipschitz functions (such a set is called epilipschitz set).

Korovkin Approximation for Weighted Set-Valued Functions

open access: yesJournal of Approximation Theory, 1999
The author studies the existence of Korovkin systems in the general setting of weighted spaces of continuous functions defined on a locally compact Hausdorff space \(X\) and with values in the set of non-empty compact convex subsets of a locally convex space \(E.\) One gives a Korovkin type approximation theorem for monotone linear operators on such ...
