Proceedings of a symposium held in Nice, France, in April 1992, on the themes of effective methods and complexity issues in commutative algebra, projective geometry, real geometry, algebraic number theory, and algebro-geometric methods in algebraic computing and applications. Papers discuss Koszul complex, Grobner bases and standard monomial theory, versal deformations of powers of volume forms, computer vision, counting real zeros in the multivariate case, locally effective objects and algebraic topology, and a parameterized nullstellensatz.
