[PDF][PDF] Some remarks on almost radiality in function spaces

G Dimov, G Tironi - Acta Universitatis Carolinae. Mathematica et Physica, 1987 - dml.cz
Recently it was proved, by Gerlits, Nagy and Szentmiklossy, that the space Cp (X) of
continuous real functions on X, with the topology of pointwise convergence, is radial if and …

Pseudoradial spaces: results and problems

G Tironi - Mediterranean Journal of Mathematics, 2006 - Springer
In this paper it is given a survey of principal results (old and new) concerning the class of
pseudoradial spaces. In this class cardinal invariants and their inequalities are considered …

A consistent σ-compact sequential space which is not hereditarily weakly Whyburn

C Costantini - Topology and its Applications, 2007 - Elsevier
We prove that under a= c (in particular, under Martin's Axiom) there exists a regular σ-
compact sequential space which is not hereditarily weakly Whyburn. This gives a consistent …

Radiality and spokes: a structural theory of convergence

R Leek - 2015 - ora.ox.ac.uk
This thesis is a wide-ranging investigation of convergence properties in topological spaces,
primarily Fréchet-Urysohn and radial spaces. The former are spaces such that every point in …

Open maps do not preserve Whyburn property

FRC ObERsnEl - Commentationes Mathematicae Universitatis Carolinae, 2003 - dml.cz
We show that a (weakly) Whyburn space $ X $ may be mapped continuously via an open
map $ f $ onto a non (weakly) Whyburn space $ Y $. This fact may happen even between …
