Abstract

Given a non-degenerate Peano continuum XX, a dimension function D:2X[0,]D:2^X_*\to[0,\infty] defined on the family 2X2^X_* of compact subsets of XX, and a subset Γ[0,)\Gamma\subset[0,\infty), we recognize the topological structure of the system (2X,\Dγ(X))αΓ(2^X,\D_{\le\gamma}(X))_{\alpha\in\Gamma}, where 2X2^X is the hyperspace of non-empty compact subsets of XX and Dγ(X)D_{\le\gamma}(X) is the subspace of 2X2^X, consisting of non-empty compact subsets KXK\subset X with D(K)γD(K)\le\gamma.
