Commutative Algebra: Constructive Methods: Finite Projective Modules
ISBN: 9789401799430 / Angielski / Twarda / 2015 / 996 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Translated from the popular French edition, this book offers a detailed introduction to various basic concepts, methods, principles, and results of commutative algebra. It takes a constructive viewpoint in commutative algebra and studies algorithmic approaches alongside several abstract classical theories. Indeed, it revisits these traditional topics with a new and simplifying manner, making the subject both accessible and innovative. The algorithmic aspects of such naturally abstract topics as Galois theory, Dedekind rings, Prufer rings, finitely generated projective modules,...

An Elementary Recursive Bound for Effective Positivstellensatz and Hilbert's 17th Problem
ISBN: 9781470441081 Termin realizacji zamówienia: ok. 30 dni roboczych. The authors prove an elementary recursive bound on the degrees for Hilbert's 17th problem. More precisely they express a nonnegative polynomial as a sum of squares of rational functions and obtain as degree estimates for the numerators and denominators the following tower of five exponentials $ 2^{ 2^{ 2^{d^{4^}} } } $ where $d$ is the number of variables of the input polynomial. The authors' method is based on the proof of an elementary recursive bound on the degrees for Stengle's Positivstellensatz. More precisely the authors give an algebraic certificate of the emptyness of the...
