A Note on Reconstruction of Spaces and Maps from Lattice Data

open access: yes, 2004
Reconstruction of topological spaces from the lattices Ω(X) of open sets, and of continuous maps from lattice homomorphisms satisfying additional properties (formulated in lattice terms) is discussed.

Some Remarks on a Theorem of H.-J. Schmidt

open access: yes, 1993
[Barov Stoyu; Баров Стою]; [Dimov George; Димов Георги]; [Nedev Stoyan; Недев Стоян]On the basis of a property of the hyperspace, H.-J. Schmidt [S] introduced implicitly a class of spaces called in the present paper HS-spaces.

SOME PROPERTIES OF J -HAUSDORFF, J -REGULAR AND J -NORMAL SPACES

open access: yes, 2018
In this paper we present new properties about the J - Hausdorff, J -regular and J -normal spaces, introduced recently by Suriyakala-Vembu. Additionally we introduce the J -Urysohn spaces, an intermediate concept between the Urysohn spaces and the J -
