Abstract
The main purpose of this paper is to introduce a some concepts in fibrewise bitopological spaces which are called fibrewise ij, fibrewise ij -closed, fibrewise ij -compact, fibrewise ij-perfect, fibrewise weakly ij-closed, fibrewise almost ij-perfect, fibrewise ij*-bitopological space respectively. In addition the concepts as ij-contact point, ij-adherent point, filter, filter base, ij-converges to a subset, ij-directed toward a set, ij-continuous, ij-closed functions, ij-rigid set, ij-continuous functions, weakly ij-closed, ij-H-set, almost ij-perfect, ij*-continuous, pairwise Urysohn space, locally ij-QHC bitopological space are introduced and the main concept in this paper is fibrewise ij-perfect bitopological spaces. Several theorems and characterizations concerning with these concepts are studied.
