Journal ArticleDOI
A Gröbner Free Alternative for Polynomial System Solving
TL;DR: A new generation of probabilistic algorithms where all the computations use only univariate or bivariate polynomials are introduced, and a new codification of the set of solutions of a positive dimensional algebraic variety is given relying on a new global version of Newton's iterator.
Journal ArticleDOI
Straight--Line Programs in Geometric Elimination Theory
TL;DR: A new method for solving symbolically zero-dimensional polynomial equation systems in the affine and toric case using Newton iteration in order to simplify straight-line programs occurring in elimination procedures and improving the well-know worst-case complexity bounds for zero- dimensional equation solving in symbolic and numeric computing.
Journal ArticleDOI
Lower bounds for diophantine approximations
TL;DR: An intrinsic lower bound for the logarithmic height of diophantine approximations to a given solution of a zero-dimensional polynomial equation system is obtained and represents a multivariate version of Liouville's classical theorem on approximation of algebraic numbers by rationals.
Book ChapterDOI
When Polynomial Equation Systems Can Be Solved Fast
TL;DR: It is possible to solve any affine or toric zero-dimensional equation system in non-uniform sequential time which is polynomial in the length of the input description and the “geometric degree” of the equation system.
