an extension of fuzzy d-subalgebras

This paper introduces the concept of l-sub d-algebras and presents the notions of (reproduced, loyal, l-edge and l-transitive) l-sub d-algebra and considers the relation between them. it presents the notion of reproduced l-sub d-algebras and investigates the relation between these concepts. we try to convert the l-sub d-algebras to l-monoids under some conditions such as loyally of l-subsets. the concepts of the stabilizer and straightener of d-algebras are introduced based on l-sub d-algebras and is tried to convert of the d-algebras to other logical algebras via the l-edge, l-transitive and loyal l-subsets
