Functionals, functors and ultrametric spaces
Pracì Mìžnarodnogo Geometričnogo Centru, 2014 We consider different classes of functionals defined on the set of continuous functions on ultrametric spaces. Similarly as in the case of probability measures, idempotent measures, max-min measures and upper semicontinuous capacities we endow the sets ...

New existence of equilibria via connectedness
International Journal of Mathematics and Mathematical Sciences, 1998 The purpose of this paper is to prove a new topological fixed point theorem by using the connectedness property, and next existence of equilibria in generalized games are established as applications.

Metric characterizations of upper semicontinuity
Journal of Mathematical Analysis and Applications, 1979 AbstractWe characterize upper semicontinuity of multifunctions in terms of upper Hausdorff semicontinuity, measure of non compactness and active boundary. The results are applicable in optimization, theory of best approximation and in metrizability theory.

Maximal elements and equilibria of generalized games for 𝒰-majorized and condensing correspondences
International Journal of Mathematics and Mathematical Sciences, 1999 In this paper, we first give an existence theorem of maximal elements for a new type of preference correspondences which are 𝒰-majorized. Then some existence theorems for compact (resp., non-compact) qualitative games and generalized games in which the ...

Sandwich-type characterization of completely regular spaces
Applied General Topology, 2007 All the higher separation axioms in topology, except for complete regularity, are known to have sandwich-type characterizations. This note provides a characterization of complete regularity in terms of inserting a continuous real-valued function.

Existence of solutions for some Hammerstein type integro-differential inclusions
Electronic Journal of Differential Equations, 2007 In the present work we obtain existence results for Hammerstein type integro-differential inclusions in a finite dimensional space for the cases when the integral multifunction satisfies upper Caratheodory conditions and when it is almost lower ...

Existence for Competitive Equilibrium by Means of Generalized Quasivariational Inequalities
Abstract and Applied Analysis, 2013 A competitive economic equilibrium model integrated with exchange, consumption, and production is considered. Our goal is to give an existence result when the utility functions are concave, proper, and upper semicontinuous.

Bounded Motions of the Dynamical Systems Described by Differential Inclusions
Abstract and Applied Analysis, 2009 The boundedness of the motions of the dynamical system described by a differential inclusion with control vector is studied. It is assumed that the right-hand side of the differential inclusion is upper semicontinuous. Using positionally weakly invariant
