摘要：
Partially ample divisors are defined by relaxing the different conditions that characterize the ample divisors. We prove that for nef and big divisors such notions coincide. We also prove that the partial ampleness of big divisors are preserved in the positive parts of the Fujita-Zariski decomposition. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
