E-core of double sequences
Sever, Yurdal; Talo, Özer (2014)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 ... -
On some classes of four dimensional regular matrices
Sever, Yurdal; Altay, Bilal (2016)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 ... -
On some double cesàro sequence spaces
Sever, Yurdal; Altay, Bilal (JSTOR, 2014)In this study, we define the double Ces`aro sequence spaces Ces_p , Ces_bp and C es bp_0 and examine some properties of those sequence spaces. Furthermore, we determine the β(bp)-duals of the spaces Ces_ bp and Ces_p . -
On statistical convergence of double sequences of closed sets
Sever, Yurdal; Talo, Özer (JSTOR, 2016)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 statistically convergent sequences of closed sets
Talo, Özer; Sever, Yurdal; Başar, Feyzi (JSTOR, 2016)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 ... -
Regularly ideal convergence and regularly ideal cauchy double sequences in 2-normed spaces
Sever, Yurdal; Dündar, Erdinç (JSTOR, 2015)In this paper, we introduce the notions of ( I_2, I), ( I^∗2 ,I^∗)-convergence and ( I_2, I), ( I^∗2, I^∗) Cauchy double sequence in regular sense in 2-normed spaces. Also, we study some properties of these concepts.
