Theta-regularity in spaces with more topologies
In this work we investigate the concept of theta-regularity generalized for spaces with two and three topologies and study its relations to bitopological paracompactness and bitopological unstability in presence of pairwise Hausdorf...

A generalization of $theta$-regularity and bitopological covering properties
In this paper we investigate the concept of $theta$-regularity generalized for spaces with two and three topologies and study its relations to bitopological separationaxiom.We also complete some author's previous results regarding g...

On 3-topological version of $theta$-regularity
In this paper we modify the concept of $theta$-regularity for spaces with two and three topologies. The new, more general property is fully preserved by sums and products. Using some bitopological reductions of this property, Michae...

On Weak Reflections in Some Superclasses of Compact Spaces II
From the general point of view, we study and characterize the spaces having a weak reflection in classes that contain the class of compact spaces and that are contained in the class of $theta$-regular spaces. Among others, we give a...

A note on paracompactness and full normality without weak separation axioms
In this paper we develop a general method which allows to omit T0 and T1 axioms in some covering theorems concerning paracompactness and full normality....
