Mappings on pairwise para-lindelo¨f bitopological spaces

The aim of this paper is to study and present the effect of some types of mapping on pairwise paralindelo¨f spaces, pairwise nearly paralindelo¨f spaces and pairwise almost paralindelo¨f spaces. The main results are that the paralindelo¨f property is not preserved under closed mappings. But it is preserved under perfect mappings in bitopological settings.
