Separation axioms in fuzzy bitopological spaces

Journal of Intelligent & Fuzzy Systems, 2014
In this paper, lattice-valued analogues of T i separation axioms for fuzzy bitopological spaces where i ∈ {0, 1, 2, 3, 4} are introduced, employing the notion of neighborhood filter of W. Gähler.

NEARLY LINDELÖFNESS IN BITOPOLOGICAL SPACES

South East Asian Journal of Mathematics and Mathematical Sciences
The concept of nearly pairwise Lindelöf spaces, a well-known weaker form of Lindelöf spaces, was introduced by Katetov and L. Krajewski in [11, 12] and has since been extensively explored by numerous researchers. This paper investigates the same concept in the context of a specific type of cover, referred to as a regular cover.

Bitopological spaces

2017
A bitopological space (X,τ,μ) is a set X with two topologies. The study of bitopological spaces was initiated by J. C. Kelly. In this thesis, we study pairwise-separation axioms as defined by J. C. Kelly, C. W. Patty, and F. P. Lane. In addition, definitions for semi-compactness, semi-paracompactness, and bicontinuous functions are proposed and are ...

Problems of the theory of bitopological spaces. II

1995
The first part [Zap. Nauchn. Semin. Leningr. Otd. Mat. Inst. Steklova 167, 5-62 (1988; Zbl 0685.54019)] of this work covers the period until 1986 inclusive and part of 1987. The second part, which we present here, mainly concerns the papers published in 1987-1990. It also replenishes the gaps concerning earlier papers, and touches some papers published

????#RG - Homeomorphisms in Bitopological Spaces

A bijection ?: (?, ?1 , ?2 ) → (?, ?1 , ?2 ) is called ?1 ?2 #regular generalized –homeomorphism if ? and ? −1 are ?1 ?2 #rg-continuous. Also we introduce new class of maps, namely ?1 ?2 #rgc-homeomorphisms which form a subclass of ?1 ?2 #rg-homeomorphisms. This class of maps is closed under composition of maps.
