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 đť’°-majorized. Then some existence theorems for compact (resp., non-compact) qualitative games and generalized games in which the ...

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.

The Class $I_0$ for Random Increasing Upper Semicontinuous Functions [PDF]
, 1999 Let C be the convex cone USC*([0, 1], R+) of increasing upper semicontinuous functions g : [0, 1] --> R+. It is shown that the class I-0(C) of distributions on C without indecomposable factor is strictly included in the class of infinitely divisible ...

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.

Upper semicontinuous fuzzy sets and applications [PDF]
, 1980 Let (X, τ) be a generalized topological space of type Vα (see A. Appert and K. Fan, “Espaces topologiques intermédiares,” Herman, Paris, 1951) and (L, ⩽) be a complete Brouwerian lattice such that the dual lattice of (L, ⩽) is also Brouwerian.

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 OF MAXIMAL ELEMENTS OF SEMICONTINUOUS PREORDERS [PDF]
, 2013 We discuss the existence of an upper semicontinuous multi-utility representation of a preorder on a topological space. We then prove that every weakly upper semicontinuous preorder $\precsim$ is extended by an upper semicontinuous preorder and use this ...

Electronic Journal of Differential Equations, 2007 This paper provide some applications of Pettis integration to differential inclusions in Banach spaces with three point boundary conditions of the form $$ ddot{u}(t) in F(t,u(t),dot u(t))+H(t,u(t),dot u(t)),quad hbox{a.e. } t in [0,1], $$ where $F$
