摘要

给定一个非退化Peano连续体X,一个定义在X的紧子集族2∗X上的维函数D:2∗X→[0,∞]和一个子集Γ∧[0,∞],我们认识到系统< 2X,D≤Γ (X) > α∈Γ的拓扑结构,其中2X是X的非空紧子集的超空间,D≤Γ (X)是2X的子空间,由D(K)≤Γ的非空紧子集K∧X组成。

The topology of systems of hyperspaces determined by dimension functions

Given a non-degenerate Peano continuum X, a dimension function D:2X[0,] defined on the family 2X of compact subsets of X, and a subset Γ[0,), we recognize the topological structure of the system 2X,Dγ(X)αΓ, where 2X is the hyperspace of non-empty compact subsets of X and Dγ(X) is the subspace of 2X, consisting of non-empty compact subsets KX with D(K)γ.
