This textbook provides an in depth and complete presentation of the linear algebra in response to axiomatic remedy of linear areas. the writer keeps a great stability among sleek algebraic pursuits and standard linear algebra. a number of chapters were considerably rewritten for readability of exposition, even though their simple content material is unchanged.

Polynomial Automorphisms: and the Jacobian Conjecture

Influenced by way of a few infamous open difficulties, corresponding to the Jacobian conjecture and the tame turbines challenge, the topic of polynomial automorphisms has turn into a swiftly transforming into box of curiosity. This ebook, the 1st within the box, collects a number of the effects scattered through the literature. It introduces the reader to a desirable topic and brings him to the leading edge of study during this region.

Modules and comodules

The 23 articles during this quantity surround the court cases of the overseas convention on Modules and Comodules held in Porto (Portugal) in 2006 and devoted to Robert Wisbauer at the social gathering of his sixty fifth birthday. those articles replicate Professor Wisbauer's huge pursuits and provides an outline of other fields relating to module thought, a few of that have an extended culture while others have emerged lately.

Lineare Algebra für Wirtschaftsinformatiker: Ein algorithmen-orientiertes Lehrbuch mit Lernsoftware

In den Wirtschaftswissenschaften werden oft praktische Probleme mit Hilfe von mathematischen Modellen analysiert, die aus Systemen von linearen Gleichungen oder Ungleichungen bestehen. Da in der Praxis Systeme mit einer groBen Anzahl von Unbekannten und vielen linearen Gleichungen auftreten, die nicht von Hand, sondem mit Hilfe von Computem gelost werden, wird im vorliegenden Buch der mathematische Stoff der linearen Algebra und linearen Optimierung vom algorith mischen Standpunkt aus behandelt.
