Book Description

Banach Limit and Applications provides all the results in the area of Banach Limit, its extensions, generalizations, and applications to various fields in one go (as far as possible). All the results in this field, after Banach introduced this concept in 1932, were scattered till now.

Sublinear functionals generating and dominating Banach Limit, unique Banach Limit (almost convergence), invariant means and invariant limits, absolute and strong almost convergence, applications to ergodicity, law of large numbers, Fourier series, uniform distribution of sequences, uniform density, core theorems, and functional Banach limits are discussed in this book. The discovery of functional analysis, such as the Hahn-Banach Theorem and the Banach-Steinhaus Theorem, helped the researchers to develop a modern, rich, and unified theory of sequence spaces by encompassing classical summability theory via matrix transformations and the topics related to sequence spaces, which arose from the concept of Banach limits, all of which are presented in this book.

The unique features of this book are as follows:

  • All the results in this area which were scattered till now are in one place.
  • The book is the first of its kind in the sense that there is no other competitive book.
  • The contents of this monograph did not appear in any book form before.

The audience of this book are the researchers in this area and Ph.D. and advanced master’s students. The book is suitable for one- or two-semester course work for Ph.D. students, M.S. students in North America and Europe, and M.Phil. and master’s students in India.
