Upper Semicontinuous Collections of Continua in Class W [PDF]
Proceedings of the American Mathematical Society, 1983 A continuum is proven to be in Class W W if it can be decomposed into an upper semicontinuous collection of

Best Proximity Pairs for Upper Semicontinuous Set-Valued Maps in Hyperconvex Metric Spaces
Fixed Point Theory and Applications, 2009 A best proximity pair for a set-valued map F:A⊸B with respect to a map g:A→A is defined, and new existence theorems of best proximity pairs for upper semicontinuous set-valued maps with respect to a homeomorphism are proved in hyperconvex ...

Discretization methods for nonconvex differential inclusions
Electronic Journal of Qualitative Theory of Differential Equations, 2009 We prove the existence of solutions for the differential inclusion $\dot x(t)\in F(t,x(t)) + f(t,x(t))$ for a multifunction $F$ upper semicontinuous with compact values contained in the generalized Clarke gradient of a regular locally Lipschitz function ...

Viable solutions for second order nonconvex functional differential inclusions
Electronic Journal of Differential Equations, 2005 We prove the existence of viable solutions for an autonomous second-order functional differential inclusions in the case when the multifunction that define the inclusion is upper semicontinuous compact valued and contained in the subdifferential of a ...

Upper semicontinuity of the lamination hull [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2018 Let K ⊆ ℝ2×2 be a compact set, let Krc be its rank-one convex hull, and let L (K) be its lamination convex hull. It is shown that the mapping K ↦ L̅(K̅) is not upper semicontinuous on the diagonal matrices in ℝ2×2, which was a problem left by Kolář. This is followed by an example of a 5-point set of 2 × 2 symmetric matrices with non-compact lamination

Upper semicontinuity of automorphism groups
Mathematische Annalen, 1994 The authors prove striking results on upper semicontinuity of automorphism groups. They show, for example, that if pairs \((M_j, G_j)\) \((M_j\) connected complex manifolds and \(G_j\) subgroups of \(\Aut (M_j))\) converge on compacta to a pair \((M,G)\), where \(M\) is a hyperbolic complex manifold and \(G\) is a subgroup of \(\Aut (M)\), then \(G_j\)

The Wu metric is not upper semicontinuous [PDF]
Proceedings of the American Mathematical Society, 2007 In this article a question asked in [\textit{M. Jarnicki} and \textit{P. Pflug}, Proc. Am. Math. Soc. 133, 239--244 (2005; Zbl 1051.32009)] is discussed, namely: Are the Wu metrics, associated to the Azukawa and the Kobayashi metric, respectively, upper semicontinuous?

A viability result for second-order differential inclusions
Electronic Journal of Differential Equations, 2002 We prove a viability result for the second-order differential inclusion $$ x''in F(x,x'),quad (x(0), x'(0))=(x_0,y_0)in Q:=Kimes Omega, $$ where $K$ is a closed and $Omega$ is an open subsets of $mathbb{R}^m$, and is an upper semicontinuous set-valued ...

Fixed point index approach for solutions of variational inequalities
International Journal of Mathematics and Mathematical Sciences, 2005 By using fixed point index approach for multivalued mappings, the existence of nonzero solutions for a class of generalized variational inequalities is studied in reflexive Banach space.

Existence of Order-Preserving Functions for Nontotal Fuzzy Preference Relations under Decisiveness
Axioms, 2017 Looking at decisiveness as crucial, we discuss the existence of an order-preserving function for the nontotal crisp preference relation naturally associated to a nontotal fuzzy preference relation.
