SEQUENCE SPACES AND NONARCHIMEDEAN ANALYSIS presents the recent developments in the areas of sequence spaces, matrix transformations and nonarchimedean analysis. The topics covered include absolute and strong almost convergence, duality in sequence spaces, functional Banach limits, matrix transformations, valued fields, Banach spaces and Banach algebras over nonarchimedean fields. Although the book starts with basic concepts, most of the results presented here did not appear in any book before. Besides being used as a text for graduate students this book will be useful as a reference book for researchers working in this field.
