Cones that are 1/2-homogeneous

Nadler, SB; Pellicer-Covarrubias, P (2007)

A space is 1/2-homogeneous provided that there are exactly two orbits for the action of 2 the group of homeomorphisms of the space onto itself. Let X be a nonempty compact metric space such that the cone over X is ...
Dendrites and light open mappings

Charatonik, JJ; Charatonik, LJ; Krupski, PL (2000)

It is shown that a metric continuum X is a dendrite if and only if for every compact space Y and for every light open mapping f : Y --> f(Y) such that X subset of f(Y) there is a copy X' of X in Y for which the restriction ...
Openness of induced projections

Charatonik, JJ; Charatonik, WJ; Illanes, A (2000)

For continua X and Y it is shown that if the projection f : X x Y --> X has its induced mapping C(f) open, then X is C-smooth. As a corollary, a characterization of dendrites in these terms is obtained.
Shore points and noncut points in dendroids

Neumann-Lara, V; Puga, I (1999)

A point p in a dendroid X is a shore point if there exists a sequence of subdendroids of X not containing p and converging to X with respect to the Hausdorff metric. The purpose of this paper is to present new results ...
