Opis

The central aim of this book is to understand modules and the categories they form through associated structures and dimensions, which reflect the complexity of these, and similar, categories. The structures and dimensions considered arise particularly through the application of model-theoretic and functor-category ideas and methods. Purity and associated notions are central, localization is an ever-present theme and various types of spectrum play organizing roles. This book presents a unified, coherent account of material which is often presented from very different viewpoints and clarifies the relationships between these various approaches.

Recenzje

'This very interesting book is written so that it will be useful for graduate students and experienced researchers. It is worth to be mentioned that Mike Prest introduced in this book some very useful appendixes which come to help the reader to become familiar with the language of model theory. The book contains a lot of illuminating examples which are also very helpful for the reader.' Zentralblatt MATH
