The d-very ampleness on a projective surface in positive characteristic

Hiroyuki Terakawa

Vol. 187 (1999), No. 1, 187–199
Abstract

M. Beltrametti and A.J. Sommese gave a numerical criterion for a line bundle on a complex projective surface to be d-very ample. In this paper, we prove that their criterion also holds on a projective surface defined over an algebraically closed field of characteristic p > 0.
