Another Sierpinski object in BFTS

Abstract

We identify a Sierpinski object in the category of fuzzy bitopological spaces, which is different from the two Sierpinski objects in this category, obtained earlier by Khastgir and Srivastava ['On two epireflective subcategories of the category of 2$T_0$-fuzzy bitopological spaces', Quaestiones Mathematicae, 23 (2000) 163-177].
