Characteristic cycles and Gevrey series solutions of $A$-hypergeometric systems [PDF]

open access: yes, 2019
We compute the $L$-characteristic cycle of an $A$-hypergeometric system and higher Euler-Koszul homology modules of the toric ring. We also prove upper semicontinuity results about the multiplicities in these cycles and apply our results to analyze the ...

Existence of random attractors and the upper semicontinuity for small random perturbations of 2D Navier-Stokes equations with linear damping

open access: yesOpen Mathematics, 2021
The incompressible 2D stochastic Navier-Stokes equations with linear damping are considered in this paper. Based on some new calculation estimates, we obtain the existence of random attractor and the upper semicontinuity of the random attractors as ε→0 ...

A Discrete Characterization of the Solvability of Equilibrium Problems and Its Application to Game Theory

open access: yesAxioms, 2023
We state a characterization of the existence of equilibrium in terms of certain finite subsets under compactness and transfer upper semicontinuity conditions.

The existence and the stability of solutions for equilibrium problems with lower and upper bounds [PDF]

open access: yes, 2012
In this paper, we study a class of equilibrium problems with lower and upper bounds. We obtain some existence results of solutions for equilibrium problems with lower and upper bounds by employing some classical fixed-point theorems.

Decomposition of Topologies Which Characterize the Upper and Lower Semicontinuous Limits of Functions

open access: yesAbstract and Applied Analysis, 2011
We present a decomposition of two topologies which characterize the upper and lower semicontinuity of the limit function to visualize their hidden and opposite roles with respect to the upper and lower semicontinuity and consequently the continuity of ...

Upper Semicontinuity of Solution Mappings to Parametric Generalized Vector Quasiequilibrium Problems

open access: yesJournal of Function Spaces, 2015
We establish the upper semicontinuity of solution mappings for a class of parametric generalized vector quasiequilibrium problems. As applications, we obtain the upper semicontinuity of solution mappings to several problems, such as parametric ...

On the upper semicontinuity of Choquet capacities

open access: yesInternational Journal of Approximate Reasoning, 2010
AbstractThe Choquet capacity T of a random closed set X on a metric space E is regarded as or related to a non-additive measure, an upper probability, a belief function, and in particular a counterpart of the distribution functions of ordinary random vectors.

Pullback Attractor for Nonautonomous Ginzburg-Landau Equation with Additive Noise

open access: yesAbstract and Applied Analysis, 2014
Long time behavior of stochastic Ginzburg-Landau equations with nonautonomous deterministic external forces, dispersion coefficients, and nonautonomous perturbations is studied. The domain is taken as a bounded interval I in R.
