Some recent algorithms in real algebraic geometry

Marie-Françoise Roy, Institut de Recherche Mathématique de Rennes, France

Abstract
Algorithms in real algebraic geometry deal with basic questions such as the computation of the number of real roots of a univariate polynomial as well as sophisticated problems such as the determination of the Betti numbers of semi-algebraic sets. Recent results clarifying the complexity of these problems will be described and some open questions will be listed.
