#### Lecture Notes on Algebraic Structure of Lattice-Ordered Rings

World Scientific Publishing Company 2014; US$ 75.00Algebraic Structure of Lattice-Ordered Rings presents an introduction to the theory of lattice-ordered rings and some new developments in this area in the last 10-15 years. It aims to provide the reader with a good foundation in the subject, as well as some new research ideas and topic in the field. This book may be used as a textbook for graduate... more...

#### Emil Artin and Helmut Hasse

Springer 2014; US$ 149.00This volume consists of the English translations of the letters exchanged between Emil Artin to Helmut Hasse written from 1921 until 1958. The letters are accompanied by extensive comments explaining the mathematical background and giving the information needed for understanding these letters. Most letters deal with class field theory and shed a light... more...

#### Where is the Gödel-point hiding

Springer 2013; US$ 54.99This book explains the first published consistency proof of PA. It contains the original Gentzen's proof, but it uses modern terminology and examples to illustrate the essential notions. The author comments on Gentzen's steps which are supplemented with exact calculations and parts of formal derivations. A notable aspect of the proof is the representation... more...

#### Cohomology of Number Fields

Springer 2013; US$ 179.00The second edition is a corrected and extended version of the first. It is a textbook for students, as well as a reference book for the working mathematician, on cohomological topics in number theory. The first part provides algebraic background: cohomology of profinite groups, duality groups, free products, and homotopy theory of modules, with new... more...

#### Algebra

De Gruyter 2013; US$ 839.00The expanded and revised new edition of this text offers an elegant and coherent introduction to the material covered in a university-level algebra course.

#### Extensions of Rings and Modules

Springer 2013; US$ 79.99The focus of this monograph is the study of rings and modules which have a rich supply of direct summands with respect to various extensions. The first four chapters of the book discuss rings and modules which generalize injectivity (e.g., extending modules), or for which certain annihilators become direct summands (e.g., Baer rings). Ring extensions... more...

#### Quadratic Irrationals

Taylor and Francis 2013; US$ 99.95Quadratic Irrationals: An Introduction to Classical Number Theory gives a unified treatment of the classical theory of quadratic irrationals. Presenting the material in a modern and elementary algebraic setting, the author focuses on equivalence, continued fractions, quadratic characters, quadratic orders, binary quadratic forms, and class groups.... more...
