On some classes of four dimensional regular matrices
(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 ... -
Regularly ideal convergence and regularly ideal cauchy double sequences in 2-normed spaces
(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. -
The effect of voltage on the arc stud welding of microwave sintered Fe+Al powder mixture
(2014)The joining of powder metallurgy products is of importance because of high demand in many industrial applications. In this study, the effect of welding voltage on the joint quality has been investigated using discharge ... -
On some double cesàro sequence spaces
(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
(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 ... -
E-core of double sequences
(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 ... -
