I_2Convergence and I_2Cauchy double sequences
Dündar, Erdinç; Altay, Bilal (ScienceDirect, 2014)In this article, we prove a decomposition theorem for I2convergent double sequences and introduce the notions of I2Cauchy and I 2 Cauchy double sequence, and then study their certain properties. Finally, we introduce ... 
I_2convergence of double sequences of functions
Dündar, Erdinç; Altay, Bilal (Electronic Journal of Mathematical Analysis and Applications, 2015)In this work, we discuss various kinds of ideal convergence for double sequences of functions with values in R. We introduce the concepts of I_2, I∗_2pointwise convergence and the concepts of I_2, I∗_2pointwise Cauchy ... 
I_2Uniform convergence of double sequences of functions
Dündar, Erdinç; Altay, Bilal (2016)In this work, we discuss various kinds of I_2uniform convergence for double sequences of functions and introduce the concepts of I_2 and I*_2uniform convergence, I2uniformly Cauchy sequences for double sequences of ... 
Multipliers for bounded I_2convergence of double sequences
Dündar, Erdinç; Altay, Bilal (2012)Multipliers and factorizations for bounded statistically convergent sequences were studied by Connor et al. [J. Connor, K. Demirci, C. Orhan, Multipliers and factorizations for bounded statistically convergent sequences, ... 
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 some properties of I_2Convergence and I_2Cauchy of double sequences
Dündar, Erdinç; Altay, Bilal (2011)In this paper we study the concepts of ICauchy and I∗Cauchy for double sequences in a linear metric space. Also, we give the relation between Iconvergence and I*convergence of double sequences of functions defined ...
