TitleA Reordered Schur Factorization Method for Zero-dimensional Polynomial Systems with Multiple Roots
Author(s) Robert M. Corless, Patrizia M. Gianni, Barry M. Trager
TypeArticle in Conference Proceedings
AbstractWe discuss the use of a single generic linear combination of multiplication matrices, and its reordered Schur factorization, to find the roots of a system of multivariate polynomial equations. The principal contribution of the paper is to show how to reduce the multivariate problem to a univariate problem, even in the case of multiple roots, in a numerically stable way.
