TITLE ON PROJECTIVE THREEFOLDS OF GENERAL TYPE WITH SMALL POSITIVE GEOMETRIC GENUS

ABSTRACT In this paper we study the pluricanonical maps of minimal projective 3-folds of general type with geometric genus 1, 2 and 3. We go in the direction pioneered by Enriques and Bombieri, and other authors, pinning down, for low projective genus, a finite list of exceptions to the birationality of some pluricanonical map. In particular, apart from a finite list of weighted baskets, we prove the birationality of phi(16), phi(6) and phi(5) respectively.
