Computational Methods in Commutative Algebra and Algebraic Geometry

Series: Algorithms and Computation in Mathematics, Vol. 2

1st ed. 1998. Corr. 2nd printing, 2004, XIII, 408 p., Softcover
ISBN: 3-540-21311-2

This ACM volume deals with tackling problems that can be represented by data structures which are essentially matrices with polynomial entries, mediated by the disciplines of commutative algebra and algebraic geometry. The discoveries stem from an interdisciplinary branch of research which has been growing steadily over the past decade. The author covers a wide range, from showing how to obtain deep heuristics in a computation of a ring, a module or a morphism, to developing means of solving nonlinear systems of equations - highlighting the use of advanced techniques to bring down the cost of computation. Although intended for advanced students and researchers with interests both in algebra and computation, many parts may be read by anyone with a basic abstract algebra course.

Symbolic Integration I, 2nd ed.
Transcendental Functions

Series: Algorithms and Computation in Mathematics, Vol. 1

2004, approx. 330 p. 3 illus., Hardcover
ISBN: 3-540-21493-3

Symbolic Integration I is destined to become the standard reference work in the field. Manuel Bronstein is a leading expert on this topic and his book is the first to treat the subject both comprehensively and in sufficient detail - incorporating new results along the way. The book addresses mathematicians and computer scientists interested in symbolic computation, developers and programmers of computer algebra systems as well as users of symbolic integration methods. Many algorithms are given in pseudocode ready for immediate implementation, making the book equally suitable as a textbook for lecture courses on symbolic integration. This second edition offers a new chapter on the Risch-Norman algorithm, a number of other improvements and a couple of additional exercises. From the reviews of the first edition: "... The writing is excellent, and the author provides a clear and coherent treatment of the problem of symbolic integration of transcendental functionsc" F. Winkler, Computing Reviews 1997

Nonlinear Differential Equation Models

2004, Approx. 190 p., Hardcover
ISBN: 3-211-20995-6

The papers in this book originate from lectures which were held at the ?Vienna Workshop on Nonlinear Models and Analysisg ? May 20?24, 2002. They represent a cross-section of the research field Applied Nonlinear Analysis with emphasis on free boundaries, fully nonlinear partial differential equations, variational methods, quasilinear partial differential equations and nonlinear kinetic models.
