The purpose of this book is to sujjest new definitions of separation axioms in fuzzy bitopological spaces. We study several features of these definitions along with the existing ones. The introduce concepts are less restrictive than those of Kandil and El-Shafee 66,67] as will be found later on. Our criteria for definitions have been preserved as much as possible the relation between the corresponding separation properties for fuzzy topological space. Moreover, it will be seen that the definitions of these axioms are "good extensions" in the sence of 92] due to Lowen. All the definitions are...

The purpose of this book is to introduce some new definitions of separation axioms in supra fuzzy topological spaces using the ideas of Ali [8]. Some of their equivalent formulations along with various new characterizations and results concerning the existing ones are presented here. Our criterion for definitions has been preserving as much as possible the relation between the corresponding separation properties for supra fuzzy topological spaces. Moreover, it will be seen that the definitions of these axioms are good extensions in the sense of Lowen [60]. We aim to develop theories of supra...
