SEMINARIO 17:00-18:00, Sala Seminari (Dip. Matematica) Betti numbers of semi-algebraic sets defined by partly quadratic systems of polynomials. Marie Francoise Roy (Universita` di Rennes)

Abstract: A recent result obtained with S. Basu and D. Pasechnik and interpolating between the classical semi-algebraic case and the purely quadratic case will be described. A list of open problems in algorithmic semi-algebraic geometry will be discussed.
