Algorithms and Computation in Mathematics #10: Algorithms in Real Algebraic Geometryby Saugata Basu
Synopses & ReviewsPublisher Comments:The algorithmic problems of real algebraic geometry such as real root counting, deciding the existence of solutions of systems of polynomial equations and inequalities, finding global maxima or deciding whether two points belong in the same connected component of a semialgebraic set appear frequently in many areas of science and engineering. In this firstever graduate textbook on the algorithmic aspects of real algebraic geometry, the main ideas and techniques presented form a coherent and rich body of knowledge, linked to many areas of mathematics and computing. Mathematicians already aware of real algebraic geometry will find relevant information about the algorithmic aspects, and researchers in computer science and engineering will find the required mathematical background. Being selfcontained the book is accessible to graduate students and even, for invaluable parts of it, to undergraduate students. This revised second edition contains several recent results, notably on discriminants of symmetric matrices, real root isolation, global optimization, quantitative results on semialgebraic sets and the first single exponential algorithm computing their first Betti number. An index of notation has also been added.
