I-Pre-Cauchy Double Sequences and Orlicz Functions

**Author(s)**Leave a comment

Let be a double sequence and let

*M*be a bounded Orlicz function. We prove that*x*is I-pre-Cauchy if and only if This implies a theorem due to Connor, Fridy and Klin [1], and Vakeel A. Khan and Q. M. Danish Lohani [2]Conflicts of Interest
