Multipliers for bounded convergent double sequences
In this paper, we investigate multipliers for bounded convergence of double sequences and study some properties and relations between l2 ∞, c2(b) and c20(b).
On statistically convergent sequences of closed sets
In this paper, we give the definitions of statistical inner and outer limits for sequences of closed sets in metric spaces. We investigate some properties of statistical inner and outer limits. For sequences of closed ...
On statistical convergence of double sequences of closed sets
In this paper, we introduce the concepts of statistical inner and statistical outer limits for double sequences of closed sets and give some formulas for ﬁnding these limits. Also, we give the Kuratowski statistical ...
On some classes of four dimensional regular matrices
In 1981, Rath and Tripathy presented some classes of regular matrices such that every bounded sequence is limitable by some member of each class of ordinary conservative matrices using ordinary sequences. The goal of ...
E-core of double sequences
Boos, Leiger and Zeller [1,2] deﬁned the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for real double sequences and prove some fundamental properties of e-limit ...
