#### Conceptual Mathematics

Cambridge University Press 2009; US$ 56.00 US$ 45.92This truly elementary book on categories introduces retracts, graphs, and adjoints to students and scientists. more...

#### Einführung in die Kategorientheorie

Springer Berlin Heidelberg 2015; US$ 18.29Die Kategorientheorie deckt die innere Architektur der Mathematik auf. Dabei werden die strukturellen Gemeinsamkeiten zwischen mathematischen Disziplinen und ihren spezifischen Konstruktionen herausgearbeitet. Dieses Buch gibt eine systematische Einführung in die Grundbegriffe der Kategorientheorie. Zahlreiche ausführliche Erklärungstexte sowie die... more...

#### The Algebra of Secondary Cohomology Operations

Birkhäuser Basel 2006; US$ 108.86The algebra of primary cohomology operations computed by the well-known Steenrod algebra is one of the most powerful tools of algebraic topology. This book computes the algebra of secondary cohomology operations which enriches the structure of the Steenrod algebra in a new and unexpected way. The book solves a long-standing problem on the algebra... more...

#### An Introduction to Homological Algebra

Springer New York 2008; US$ 34.22A fully updated edition of Rotman?s easy-to-follow, step-by-step guide to the subject. The book gives a treatment of homological algebra which approaches the subject in terms of its origins in algebraic topology. The author has included material about homotopical algebra, alias K-theory. more...

#### Threading Homology through Algebra

Clarendon Press 2006; US$ 149.99 US$ 128.99Aimed at graduate students and researchers in mathematics, this book takes homological themes, such as Koszul complexes and their generalizations, and shows how these can be used to clarify certain problems in selected parts of algebra, as well as their success in solving a number of them. more...

#### Towards Higher Categories

Springer New York 2009; US$ 130.64The purpose of this book is to give background for those who would like to delve into some higher category theory. It is not a primer on higher category theory itself. It begins with a paper by John Baez and Michael Shulman which explores informally, by analogy and direct connection, how cohomology and other tools of algebraic topology are seen through... more...

#### Relative Homological Algebra

De Gruyter 2011; US$ 152.37This second volume deals with the relative homological algebra of complexes of modules and their applications. It is a concrete and easy introduction to the kind of homological algebra which has been developed in the last 50 years. The book serves as a bridge between the traditional texts on homological algebra and more advanced topics... more...

#### Relative Homological Algebra

De Gruyter 2011; US$ 141.48This is the second revised edition of an introduction to contemporary relative homological algebra. It supplies important material essential to understand topics in algebra, algebraic geometry and algebraic topology. Each section comes with exercises providing practice problems for students as well as additional important results for specialists.... more...

#### Homological Algebra

World Scientific Publishing Company 2012; US$ 102.00In this book we want to explore aspects of coherence in homological algebra, that already appear in the classical situation of abelian groups or abelian categories. Lattices of subobjects are shown to play an important role in the study of homological systems, from simple chain complexes to all the structures that give rise to spectral sequences. A... more...

#### An Introduction to Homological Algebra

Cambridge University Press 1995; US$ 52.00 US$ 42.64A portrait of the subject of homological algebra as it exists today. more...
