Zhou, H., The chromatic difference sequence of the Cartesian product of graphs: Part II, Discrete Applied Mathematics 41 (1993) 263-267. This paper is a continuation of our earlier paper under the same title. We prove that the normalized chromatic difference sequences of the Cartesian powers of a Cayley graph on a finite Abelian group are stable; and that if the chromatic difference sequence of...

In this paper we introduce some double entire difference sequence spaces of fuzzy numbers defined by a sequence of Orlicz functions M = (Mk,l). We also make an effort to study some topological properties and some inclusion relations between these spaces.
