Summability Methods for Double Set Sequences : Theory and Applications: Applications to Wijsman Convergence of Double Sequence of Sets

This book contains a detailed study of the most popular summability methods and their applications, in particular, in Wijsman statistical and invariant convergence for double sequences of sets using modulus function. It is intended as a reference book for further work and research on Wijsman convergence in higher-dimensional sequence spaces. It can also be used for seminar work and master's and Ph.D. theses. The book is self-contained and comprehensive. It also provides the basic tools for researchers using directly or indirectly the notion of sequences and series and their convergence problems using modern summability methods. This book is intended for graduate students and researchers who have an interest in sequence spaces, summability methods and their applications, functional analysis in particular, and summability theory in general.
