Speaker Prof. Marie-Françoise ROY
Affiliation  Université de Rennes 1
Domain Algebraic Geometry
Title Real algebraic geometry and algorithms
Abstract The talk starts with a basic mathematical problem: How many roots for a real univariate polynomial? This problem was studied by Descartes, Sturm and Hermite and their algorithmic methods are still important today. A vast multivariate generalization is due to Tarski, with his famous quantifier elimination result. Various methods for quantifier elimination will be presented, and their algorithmic complexity will be discussed.
