'This comprehensive treatment of Homological Methods in Banach Space Theory by two authors who are among the most adept at using algebraic tools in functional analysis is a must for every mathematician who is interested in the geometry of Banach spaces.' William B. Johnson, Texas A&M University 'Commutative diagrams are a natural and concise method of encoding information about various mathematical objects, and they deserve to better known. Together with other categorical constructions such as ultrapowers, pullbacks and pushouts, they provide a big picture view and a framework for further progress. This book gives a comprehensive account of the applications of such techniques to numerous aspects of Banach spaces.' David Yost, Federation University 'This masterpiece seemingly is an excellent math book saturated with lush insights and marvellous perspectives on Banach spaces. But start to read it. When furniture and people start to appear to you as diagrams you will realize that you are in the middle of a fascinating wildlife event.' Piotr Koszmider, Institute of Mathematics of the Polish Academy of Sciences
