When deviation happens between rough statistical convergence and rough weighted statistical convergence

Sanjoy Ghosal and Avishek Ghosh
From the journal Mathematica Slovaca


In this paper we introduce rough weighted statistical limit set and weighted statistical cluster points set which are natural generalizations of rough statistical limit set and statistical cluster points set of double sequences respectively. Some new examples are constructed to ensure the deviation of basic results. Both the sets don’t follow the usual extension properties which will be discussed here.
