The Topology of Systems of Hyperspaces Determined by Dimension Functions

چکیده
Given a non-degenerate Peano continuum X, a dimension function D : 2∗ → [0,∞] defined on the family 2 X ∗ of compact subsets of X, and a subset Γ ⊂ [0,∞), we recognize the topological structure of the system 〈2 ,D≤γ(X)〉α∈Γ, where 2 X is the hyperspace of non-empty compact subsets of X and D≤γ(X) is the subspace of 2 X , consisting of non-empty compact subsets K ⊂ X with D(K) ≤ γ.

The Wijsman structure of a quantale-valued metric space
We define and study a quantale-valued Wijsman structure on the hyperspace of all non-empty closed sets of a quantale-valued metric space. We show its admissibility and that the metrical coreflection coincides with the quantale-valued Hausdorff metric and that, for a metric space, the topological coreflection coincides with the classical Wijsman topology. We further define an index of compactnes...
متن کاملFuzzy Inner Product and Fuzzy Norm \of Hyperspaces
We introduce and study fuzzy (co-)inner product and fuzzy(co-)norm of hyperspaces. In this regard by considering the notionof hyperspaces, as a generalization of vector spaces, first we willintroduce the notion of fuzzy (co-)inner product in hyperspaces and will apply it to formulate the notions offuzzy (co-)norm and fuzzy (co-)orthogonality in hyperspaces. Inparticular, we will prove that ...
متن کاملAN INDUCTIVE FUZZY DIMENSION
Using a system of axioms among with a modified definition of boundary on the basis of the intuitionistic fuzzy sets, we formulate an inductive structure for the dimension of fuzzy spaces which has been defined by Coker. This new definition of boundary allows to characterize an intuitionistic fuzzy clopen set as a set with zero boundary. Also, some critical properties and applications are establ...
متن کاملTOPOLOGY OPTIMIZATION OF STRUCTURES UNDER TRANSIENT LOADS
In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...
متن کاملTOPOLOGY OPTIMIZATION OF PLANE STRUCTURES USING BINARY LEVEL SET METHOD AND ISOGEOMETRIC ANALYSIS
This paper presents the topology optimization of plane structures using a binary level set (BLS) approach and isogeometric analysis (IGA). In the standard level set method, the domain boundary is descripted as an isocountour of a scalar function of a higher dimensionality. The evolution of this boundary is governed by Hamilton–Jacobi equation. In the BLS method, the interfaces of subdomai...
