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 ... -
On the fine spectrum of the upper triangle double band matrix Δ+ on the sequence space c0
Dündar, Erdinç; Başar, Feyzi (2013)In this study, we determine the fine spectrum of the matrix operator ∆+ defined by an upper triangle double band matrix acting on the sequence space c_0 with respect to the Goldberg’s classification. As a new development, ... -
Regularly (I_2, I)-convergence and regularly (I_2, I)-Cauchy double sequences of fuzzy numbers
Dündar, Erdinç; Talo, Özer; Başar, Feyzi (2013)In this paper, we introduce the notions of regularly, (I_2,I)-convergence and regularly, (I_2,I)-Cauchy double sequence of fuzzy numbers. Also, we study some properties of these concepts. -
The space Lq of double sequences
Başar, Feyzi; Sever, Yurdal (Department of Mathematics, Faculty of Science, Okayama University, 2009-01)The spaces BS, BS(t), CSp, CSbp, CSr and BV of double sequences have recently been studied by Altay and Başar [J. Math. Anal. Appl. 309(1)(2005), 70–90]. In this work, following Altay and Başar [1], we introduce the ...
