Hyperspaces of Peano continua of euclidean spaces

Gladdines H. , van Mill J.

nr 2

173-188

If X is a space then L(X) denotes the subspace of C(X) consisting of all Peano (sub)continua. We prove that for n ≥ 3 the space $L(ℝ^n)$ is homeomorphic to $B^∞$, where B denotes the pseudo-boundary of the Hilbert cube Q.

Selections and near-selections in metric linear spaces without local convexity

100%

Dobrowolski T. , van Mill J.

tom 192

nr 3

215-232

We characterize the AR property in convex subsets of metric linear spaces in terms of certain near-selections.

Selections that characterize topological completeness

nr 2

127-141

We show that the assertions of some fundamental selection theorems for lower-semicontinuous maps with completely metrizable range and metrizable domain actually characterize topological completeness of the target space. We also show that certain natural restrictions on the class of the domains change this situation. The results provide in particular answers to questions asked by Engelking, Heath and Michael [3] and Gutev, Nedev, Pelant and Valov [5].
