| 英文摘要 | Let X be a smooth projective variety over an algebraically closed field K with arbitrary characteristic. Suppose L is an ample and globally generated line bundle. By Castelnuovo-Mumford regularity, we show that K-X circle times L-circle times dimX circle times A is globally generated and K-X circle times L circle times(dimX+1) circle times A is very ample, provided the line bundle A is nef but not numerically trivial. On complex projective varieties, by investigating Kawamata-Viehweg-Nadel type vanishing theorems for vector bundles, we also obtain the global generation for adjoint vector bundles. In particular, for a holomorphic submersion f : X -> Y with L ample and globally generated, and A nef but not numerically trivial, we prove the global generation of f(*) (K-X/Y)(circle times s) K-Y circle times L-circle times dim Y circle times A for any positive integer s. |
