Pluricanonical systems for 3-folds and 4-folds of general type
Published online by Cambridge University Press: 19 October 2011
Abstract
We explicitly find lower bounds on the volume of threefolds and fourfolds of general type in order to have non-vanishing of pluricanonical systems and birationality of pluricanonical maps. In the case of threefolds of large volume, we also give necessary and sufficient conditions for the fourth canonical map to be birational.
