Weaker forms of the Menger property in Bitopological spaces
, 2018 In this paper we continue previous investigations on the weaker forms of the Menger property in bitopological spaces. We introduce weakly Menger property and study some topological properties of almost and weakly Menger bitopological spaces.

Some notes on Quasi-Lindelof spaces
, 2017 In this note we address a problem that was suggested by Petra Staynova in [6] regarding quasi-Lindelof spaces, and continue to study topological properties of quasi-Lindelof spaces.

, 2004 We introduce the notion of uniform paracompactness to uniform frames and give several characterisations thereof. In another context, we show that the locally fine reflector commutes with the completion in the category of strong nearness frames ...

, 2004 It is shown that the categories of stably continuous σ-frames and compact regular σ-biframes are equivalent. This is the analogue of Banaschewski and Brümmer [1], linking the stably continuous frames and compact regular biframes ...

On τ−covers using ideals and some of its consequences
, 2019 In this paper we primarily introduce an ideal version of τ-covers studied in [18, 19]. We establish the inter-relationships between I-τ-covers and I-γ , I-large [3, 5] and κ-covers[2, 7].

A note on weakly Lindelöf frames
, 2018 The notion of σ*-properness of a subset of a frame is introduced. Using this notion, we give necessary and sufficient conditions for a frame to be weakly Lindelöf .

Spread Uniformities and Uniform Spreads
, 2004 We discuss a point free analog of the topological fact that every uniformly continuous function on a dense subspace of a uniform space into a complete uniform space has a unique continuous extension. It is shown that a uniform frame homomorphism h:

Remarks on w-domination of discrete subspaces
, 2019 Given a space X, we will say that a class A of subsets of X is dominated by a class B if for any A ∈ A, there exists a B ∈ B such that A ⊂ B̅. In particular, all (closed) discrete subsets of X are countably dominated (which we frequently abbreviate as w ...
