Basepoint freeness for nef and big line bundles in positive characteristic
, 1998 A necessary and sufficient condition is given for semi-ampleness of a numerically effective (nef) and big line bundle in positive characteristic. One application is to the geometry of the universal stable curve over M_g, specifically, the semi-ampleness ...
