AN INTRODUCTION TO 0 −DENSITY AND 0 −DENSE ACE

In this paper, we introduce a concept of the 0 − limits of vector and multiple valued sequences in R m . Using this concept, we study about the concept of the 0 −dense subset and of the points of 0 −dense ace in the open subset of R m . We also investigate the properties and the characteristics of the 0 −dense subsets and of the points of 0 −dense ace.
