Matrix transforms between sequence spaces defined by speeds of convergence

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 ...

Double Sequence Spaces and Almost Convergence

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 ...

On the Convergence and Limits of Certain Matrix Sequences Arising in Quasi-Birth-and-Death Markov Chains

Journal of Applied Probability, Vol. 38, No. 2 (Jun., 2001), pp. 519-541 (23 pages) We study the convergence of certain matrix sequences that arise in quasi-birth-and-death (QBD) Markov chains and we ...

Statistical Convergence of Complex Uncertain Sequences

The study of statistical convergence of complex uncertain sequences bridges classical analysis with uncertainty quantification, addressing challenges inherent in systems where outcomes are not ...
