Let X, Y be two sequence spaces defined by speeds of the convergence, i.e.; by monotonically increasing positive sequences. In this paper, we give necessary and sufficient conditions for a matrix A ...

Abstract. The aim of paper is to define and study some ideal convergent sequence spaces with the help of generalized difference matrix B (m) n and Orlicz functions. We also make an effort to study ...

Double sequence spaces extend the classical notion of sequence spaces to encompass two-indexed structures, thereby providing a robust framework for the analysis of functions and operators in multi ...
