Geometry Today: Giornate Di Geometria, Roma, 1984: International Conference, Rome, June 4-11, 1984 (Progress in Mathematics (Birkhauser Boston))

The conference »Giornate di Geometria« was beld in Rome in June 1984. Tbe Proceedings of tbis conference offer a remarkable view of tbe state of tbe art in many fields of Geometry, ranging from tbe tbeory of algebraic groups to tbe tbeory of algebraic curves and their connections witb matbematical pbysics, differential geometry and algebraic topology. Tbis publication should be very useful for Pb. D. students and researcbers in matbematics wishing to bave an extended account of tbe present trends in tbese fields.
