In 2014, Aktu?lu 1 first introduced the notion of ??-statistical convergence which is more general than the notion of statistical convergence and lacunary statistical convergence. In this paper, based on this notion, we introduce the notion of ??-statistical convergence and ??-strongly summability for multiset sequences which improves the results in 3, 7. We investigated the relations between these two notions and presented several examples corresponding to our results. We also introduce the notion of ?? statistically limit superior and limit inferior for multiset sequences by using the notion of ?? density which improves the results in 3.
Som et al. (Wed,) studied this question.
