On the canonical maps of nonsingular threefolds of general type
arXiv:1612.06974
Abstract
Let be a nonsingular minimal complex projective surface of general type and the canonical map of is generically finite. Beauville showed that the geometric genus of the image of the canonical map is vanishing or equals the geometric genus of and discussed the canonical degrees for these two cases. We generalize his results to nonsingular minimal complex projective threefolds.
