### About this book

- Offers notes and exercises related to the topic
- Presents open problems and possible directions of research in each chapter
- Reviews current avenues of research in biorthogonal systems in Banach spaces

The main theme of this book is the relation between the global structure
of Banach spaces and the various types of generalized "coordinate
systems" - or "bases" - they possess. This subject is not new and has
been investigated since the inception of the study of Banach spaces. In
this book, the authors systematically investigate the concepts of
Markushevich bases, fundamental systems, total systems and their
variants. The material naturally splits into the case of separable
Banach spaces, as is treated in the first two chapters, and the
nonseparable case, which is covered in the remainder of the book. This
book contains new results, and a substantial portion of this material
has never before appeared in book form. The book will be of interest to
both researchers and graduate students.

Topics covered in this book include:

- Biorthogonal Systems in Separable Banach Spaces

- Universality and Szlenk Index

- Weak Topologies and Renormings

- Biorthogonal Systems in Nonseparable Spaces

- Transfinite Sequence Spaces

- Applications
