Algebra. Rings, modules and categories

VI of Oregon lectures in 1962, Bass gave simplified proofs of a few "Morita Theorems", incorporating principles of Chase and Schanuel. one of many Morita theorems characterizes whilst there's an equivalence of different types mod-A R::! mod-B for 2 jewelry A and B. Morita's resolution organizes principles so successfully that the classical Wedderburn-Artin theorem is an easy outcome, and additionally, a similarity type [AJ within the Brauer staff Br(k) of Azumaya algebras over a commutative ring okay comprises all algebras B such that the corresponding different types mod-A and mod-B such as k-linear morphisms are an identical by means of a k-linear functor.

Matrix Partial Orders, Shorted Operators and Applications (Series in Algebra)

The current monograph on matrix partial orders, the 1st in this subject, makes a different presentation of many partial orders on matrices that experience involved mathematicians for his or her good looks and utilized scientists for his or her wide-ranging software strength. apart from the LÃ¶wner order, the partial orders thought of are quite new and got here into being within the overdue Seventies.

Geometry and Algebra in Ancient Civilizations

Initially, my goal used to be to jot down a "History of Algebra", in or 3 volumes. In getting ready the 1st quantity I observed that during old civiliza­ tions geometry and algebra can't good be separated: a growing number of sec­ tions on historic geometry have been additional. accordingly the recent name of the e-book: "Geometry and Algebra in old Civilizations".
