Linear Algebra (Graduate Texts in Mathematics, Volume 23)

This textbook supplies an in depth and entire presentation of the linear algebra according to axiomatic remedy of linear areas. the writer keeps an outstanding stability among smooth algebraic pursuits and conventional linear algebra. a number of chapters were considerably rewritten for readability of exposition, even though their easy content material is unchanged.

Polynomial Automorphisms: and the Jacobian Conjecture

Encouraged by means of a few infamous open difficulties, comparable to the Jacobian conjecture and the tame turbines challenge, the topic of polynomial automorphisms has turn into a speedily starting to be box of curiosity. This booklet, the 1st within the box, collects the various effects scattered during the literature. It introduces the reader to a desirable topic and brings him to the vanguard of study during this region.

Modules and comodules

The 23 articles during this quantity surround the lawsuits of the overseas convention on Modules and Comodules held in Porto (Portugal) in 2006 and devoted to Robert Wisbauer at the get together of his sixty fifth birthday. those articles replicate Professor Wisbauer's large pursuits and provides an outline of alternative fields on the topic of module thought, a few of that have an extended culture while others have emerged in recent times.

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.
