Pluri-canonical maps of varieties of maximal Albanese dimension in positive characteristic
arXiv:1203.1360
Abstract
We show that if X is a nonsingular projective variety of general type over an algebraically closed field k of positive characteristic and X has maximal Albanese dimension and the Albanese map is separable, then |4K_X| induces a birational map.
