Reviews of Volume 1: '... this is a book that I would recommend to any student of mine, for clarity and completeness of exposition ... Any expert as well would enjoy the book and learn something stimulating from the sidenotes that point to alternative developments. We look forward to volumes two and three!' Mathematical Reviews 'The book is very well organized and carefully written. It could be particularly useful for analysts wanting to learn new methods coming from algebraic geometry.' EMS Newsletter Review of Volume 2: 'As with the first part, the book is very well written and carefully organised and it is a pleasure to read it.' EMS Newsletter
