A note on convexity and semicontinuity of fuzzy mappings
By using parameterized representation of fuzzy numbers, criteria for a lower semicontinuous fuzzy mapping defined on a non-empty convex subset of Rn to be a convex fuzzy mapping are obtained. c © 2007 Elsevier Ltd. All rights reserved.
متن کاملOn the Upper and Lower Semicontinuity of the Aumann Integral
Let (T,r,p) be a finite measure space, X be a Banach space, P be a metric space and let L,(y,X) denote the space of equivalence classes of X-valued Bochner integrable functions on (T, T, p). We show that if $I: T x P-2x is a set-valued function such that for each fixed p E P, 4(. , p) has a measurable graph and for each fixed TV T, 4(t;) is either upper or lower semicontinuous then the Aumann i...
متن کاملConvergence of Set-valued Mappings: Equi-outer Semicontinuity
The concept of equi-outer semicontinuity allows us to relate the pointwise and the graphical convergence of set-valued-mappings. One of the main results is a compactness criterion that extends the classical Arzelà-Ascol̀ı Theorem for continuous functions to this new setting; it also leads to the exploration of the notion of continuous convergence. Equi-lower semicontinuity of functions is relate...

Graph Mappings and Poincaré Duality
defined by the cap product with the fundamental class [M ] of M is an isomorphism of finitely generated abelian groups. This duality is manifest in many ways in geometry. Locally it corresponds to the duality of forms and currents in the theory of de Rham. It appears in Hodge theory via the *operator on harmonic forms. In Poincaré’s original work it can be described via barycentric subdivision ...
