It is shown that the family of all homogeneous continua in the hyperspace of all subcontinua of any finite-dimensional Euclidean cube or the Hilbert cube is an analytic subspace of the hyperspace which contains a topological copy of the linear space

Let X be a nondegenerate Peano unicoherent continuum. The family C B ( X ) of proper subcontinua of X with connected boundaries is a G δ -subset of the hyperspace C ( X ) of all subcontinua of X. If every nonempty open subset of X contains an open s

We prove that the homeomorphism relation between compact spaces can be continuously reduced to the homeomorphism equivalence relation between absolute retracts, which strengthens and simplifies recent results of Chang and Gao, and Cieśla. It follows

The family of all subcontinua that separate a compact connected n -manifold X (with or without boundary), n ≥ 3 , is an F σ -absorber in the hyperspace C ( X ) of nonempty subcontinua of X . If D 2 ( F σ ) is the small Borel class of spaces which

Given a metric continuum X, let 2 X and C ( X ) denote the hyperspaces of all nonempty closed subsets and subcontinua, respectively. For A , B ∈ 2 X we say that B does not block A if A ∩ B = ∅ and the union of all subcontinua of X intersecting

Locally connected continua which admit monotone maps onto graphs are characterized. A notion of a G -structure is introduced for any graph G as a generalization of a linear or circular chain (of arbitrary finite length) cover of a continuum by its su

The family of Wilder continua in the cube I n and its two subfamilies—of continuum-wise Wilder continua and of hereditarily arcwise connected continua—are recognized as coanalytic absorbers in the hyperspace C ( I n ) of subcontinua of I n for 3

At the end of World War 2, the Yalta/Potsdam Agreements made Lwow part of the Soviet Union’s Ukraine Republic, and the Silesian capital, Wroclaw, part of Poland. Most of the faculty of the Lwow’s Jan Casimir University moved 320 miles west to the

It is shown that a metric continuum X X is a dendrite if and only if for every compact space (continuum) Y Y and for every light confluent mapping f : Y → f ( Y ) f: Y \to f(Y) such that X ⊂ f ( Y ) X \subset f(Y) there is a copy X ′ X’ of X
