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?

Fuzzy‐Fractional Modeling and Analysis of Tobacco Smoking Dynamics via He–Laplace–Carson Framework
Journal of Mathematics, Volume 2026, Issue 1, 2026.This study develops a fuzzy‐fractional nonlinear tobacco smoking model by incorporating triangular fuzzy numbers and Caputo fractional derivative. The He–Laplace–Carson algorithm is used to solve and analyze the uncertainties and memory dependent effects involved in potential smokers, mild smokers, regular smokers, and quit smokers.

Connectedness and Contractibility of Solutions in Set Optimization Under Set Less Order Relations
Journal of Mathematics, Volume 2026, Issue 1, 2026.This study establishes the topological properties of solution sets in set optimization, focusing on their connectedness and contractibility. Utilizing the arcwise convexity and lower semicontinuity characteristics derived from scalarization techniques, we initially prove the connectedness of solution sets containing both weak and standard approximate ...

Upper Semicontinuity of Attractors for Small Random Perturbations of Dynamical Systems [PDF]
, 1998 The relationship between random attractors and global attractors for dynamical systems is studied. If a partial differential equation is perturbed by an ²¡small random term and certain hypotheses are satisfied, the upper semicontinuity of the random ...

Nonautonomous attractors of skew-product flows with digitized driving systems
Electronic Journal of Differential Equations, 2001 The upper semicontinuity and continuity properties of pullback attractors for nonautonomous differential equations are investigated when the driving system of the generated skew-product flow is digitized.

Equilibrium Existence in First‐Price Auctions With Private Values
Econometrica, Volume 94, Issue 1, Page 193-224, January 2026.We provide sufficient conditions for equilibrium existence in first‐price auctions with private values that accommodate non quasi‐linear utilities and value‐distributions that contain atoms and exhibit positive or negative correlation. These conditions show that equilibrium existence often turns on properties of a single statistic of the joint ...

UPPER SEMICONTINUITY OF THE ATTRACTOR FOR LATTICE DYNAMICAL SYSTEMS OF PARTLY DISSIPATIVE REACTION-DIFFUSION SYSTEMS [PDF]
, 2020 We investigate the existence of a global attractor and its upper semicontinuity for the infinite-dimensional lattice dynamical system of a partly dissipative reaction-diffusion system in the Hilbert space l 2 × l 2 .

Maximal elements of quasi upper semicontinuous preorders on compact spaces [PDF]
, 2017 We introduce the concept of quasi upper semicontinuity of a not necessarily total preorder on a topological space and we prove that there exists a maximal element for a preorder on a compact topological space provided that it is quasi upper ...

Existence and continuity of global attractors for a degenerate semilinear parabolic equation
Electronic Journal of Differential Equations, 2009 In this article, we study the existence and the upper semicontinuity with respect to the nonlinearity and the shape of the domain of global attractors for a semilinear degenerate parabolic equation involving the Grushin operator.

Semicontinuity of the Solution Mapping to a Parametric Generalized Weak Ky Fan Inequality
Abstract and Applied Analysis, 2014 Under new assumptions, which do not contain any information about the solution set, the upper and lower semicontinuity of the solution mapping to a class of parametric generalized weak Ky Fan inequality are established by using a nonlinear scalarization ...
