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.
