Dual spaces of geodesic currents

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Upper Semicontinuity of Attractors for a Non-Newtonian Fluid under Small Random Perturbations

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the limiting behavior of attractors for a two-dimensional incompressible non-Newtonian fluid under small random perturbations. Under certain conditions, the upper semicontinuity of the attractors for diminishing perturbations is ...

Upper semicontinuous decompositions of developable spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1965
Presented here are theorems concerning upper semicontinuous decompositions of developable spaces, topological in the sense that the common parts of intersecting domains (open sets) are open. Theorem 1 shows that, if the elements of such a decomposition do not have nonbicompact [I] intersections with the closures of their complements, the decomposition ...

Super‐Nash Performance

open access: yesInternational Economic Review, Volume 66, Issue 4, Page 1487-1503, October 2025.
ABSTRACT In this paper, I introduce a novel benchmark in games, super‐Nash performance, and a solution concept, optimin, whereby players maximize their minimal payoff under unilateral profitable deviations by other players. Optimin achieves super‐Nash performance in that, for every Nash equilibrium, there exists an optimin where each player not only ...

Upper Semicontinuous Decompositions of the n-Sphere [PDF]

open access: yesProceedings of the American Mathematical Society, 1962
We consider conditions under which an upper semicontinuous decomposition has the decomposition space which is a topological nsphere. A special emphasis is placed on the case in which the decomposition has only a countable number of nondegenerate elements.

The relative Hodge–Tate spectral sequence for rigid analytic spaces

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 4, October 2025.
Abstract We construct a relative Hodge–Tate spectral sequence for any smooth proper morphism of rigid analytic spaces over a perfectoid field extension of Qp$\mathbb {Q}_p$. To this end, we generalise Scholze's strategy in the absolute case by using smoothoid adic spaces.

Existence and Upper Semicontinuity of Attractors for Nonautonomous Stochastic Sine-Gordon Lattice Systems with Random Coupled Coefficients

open access: yesDiscrete Dynamics in Nature and Society, 2016
We study nonautonomous stochastic sine-Gordon lattice systems with random coupled coefficients and multiplicative white noise. We first consider the existence of random attractors in a weighted space for this system and then establish the upper ...

Perturbation of the diffusion and upper semicontinuity of attractors

open access: yesApplied Mathematics Letters, 1999
The authors deal with the long-time behaviour of parabolic problems with nonlinear boundary conditions. Under some natural conditions both on growth and sign conditions on nonlinearities the authors obtain uniform bounds for attractors corresponding to semigroups.

New fiber and graph combinations of convex bodies

open access: yesMathematika, Volume 71, Issue 4, October 2025.
Abstract Three new combinations of convex bodies are introduced and studied: the Lp$L_p$ fiber, Lp$L_p$ chord, and graph combinations. These combinations are defined in terms of the fibers and graphs of pairs of convex bodies, and each operation generalizes the classical Steiner symmetral, albeit in different ways.
