Taschenbuch. Condizione: Neu. Neuware - Commutative Algebra is best understood with knowledge of the geometric ideas that have played a great role in its formation, in short, with a view towards algebraic geometry. The author presents a comprehensive view of commutative algebra, from basics, such as localization and primary decomposition, through dimension theory, differentials, homological methods, free resolutions and duality, emphasizing the origins of the ideas and their connections with other parts of mathematics. Many exercises illustrate and sharpen the theory and extended exercises give the reader an active part in complementing the material presented in the text. One novel feature is a chapter devoted to a quick but thorough treatment of Grobner basis theory and the constructive methods in commutative algebra and algebraic geometry that flow from it. Applications of the theory and even suggestions for computer algebra projects are included. This book will appeal to readers from beginners to advanced students of commutative algebra or algebraic geometry. To help beginners, the essential ideals from algebraic geometry are treated from scratch. Appendices on homological algebra, multilinear algebra and several other useful topics help to make the book relatively self- contained. Novel results and presentations are scattered throughout the text.…

Taschenbuch. Condizione: Neu. Neuware -This text for advanced undergraduates emphasizes the logical connections of the subject. Elementary techniques from complex analysis, matrix theory, and group theory are used, and some mathematical sophistication on the part of students is thus required, but a formal course in these topics is not a prerequisite.…

For one thing, it was a strong element in his appeal to Elizabethans, who were much less woolly-mouthed and smooth-tongued than we are.

Buch. Condizione: Neu. Neuware - It is said that business re-engineering is part of our transition to a post-industrial society. The purpose of this book is to present an approach to how to reorganize businesses using the discipline of software engineering as a guiding paradigm. The author's thesis is that software engineering provides the necessary analytical expertise for defining business processes and the tools to transform process descriptions to support systems. The author begins by introducing the concepts and needs for business reengineering and principles and practice of software engineering. He then shows how by concentrating on processes, a business can define the information base required and how it is to be constructed. As a result, any manager or technically-minded person will learn how to implement the reengineering of a business.…
