Solving polynomial systems by polyhedral homotopy
Prof. T.Y. Li

Recently, a major computational breakthrough has emerged in solving
polynomial systems by the homotopy continuation method. The Bernstein theory
in combinatoial geometry comes to provide a much tighter bound of the root
count, usually measured by the Bezout number. When this bound is employed in
the homotopy algorithm, a great amount of computation is saved. The basic
idea will be presented in this talk.
