Upper semicontinuous representations of interval orders

Mathematical Social Sciences, 2014
Given an interval order on a topological space, we characterize its representability by means of a pair of upper semicontinuous real-valued functions. This characterization is only based on separability and continuity conditions related to both the interval order and one of its two traces.

Absolute upper semicontinuity

Mathematical Notes of the Academy of Sciences of the USSR, 1977
It is proved that the following conditions are equivalent: the function ϕ [a, b]→R is absolutely upper semicontinuous (see [1]); ϕ is a function of bounded variation with decreasing singular part; there exists a summable function g: [a, b] → R such that for anyt′∈[a, b] andt″∈[t′, b], we have ϕ(t″)−ϕ(t′)⩽∫ t′ t″ g (s) ds.

Upper semicontinuity of parametric projections

Set-Valued Analysis, 1996
In this paper we study upper semicontinuity of the metric projection P Γ(p)(x) with respect to (x, p), where x is a point in a normed linear space X and Γ(p) is an approximatively compact subset of X depending on a parameter p. An application to parametric spline approximation is given.

Upper semicontinuity of attractors for the reaction diffusion equation

Communications in Nonlinear Science and Numerical Simulation, 1996
This paper deals with the reaction diffusion equation in domain Ω = R or Ω = (−L,L) with L < ∞ Let AL and A be the global attractor of this equation corresponding to Ω = (−L,L) and Ω = R, respectively. We show that the global attractor A is upper semicontinuity at 0 with respect to the sets {AL} in some sense.

Upper Semicontinuity of Duality and Preduality Mappings [PDF]

open access: possible, 2013
In their paper studying Hausdorff weak upper semicontinuity of duality and preduality mappings on the dual of a Banach space, Godefroy and Indumathi related these by an interesting geometrical property. This property actually characterises Hausdorff upper semicontinuity of the preduality mapping.
