The space Lq of double sequences
(Department of Mathematics, Faculty of Science, Okayama University, 200901)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 ... 
I_σconvergence
(Department of Mathematics, University of Osijek, 2011)In this paper, the concepts of σuniform density of subsets A of the set N of positive integers and corresponding I_σconvergence were introduced. Furthermore, inclusion relations between I_σconvergence and invariant ...

Lacunary statistical convergence of sequences of sets
(Canadian Research & Development Center of Sciences and Cultures, 2012)Several notions of convergence for subsets of metric space appear in the literature. In this paper we deﬁne lacunary statistical convergence for sequences of sets and study in detail the relationship between other convergence ...
