A Remark on the Base Point Free Theorem
We give a remark on the Kawamata-Shokurov base point free theorem. We reprove the main theorem of Kawamata’s paper: Pluricanonical systems on minimal algebraic varieties, without using the notion of generalized normal crossing varieties.
متن کاملBase Point Free Theorem of Reid-fukuda Type
Let (X,∆) be a proper dlt pair and L a nef Cartier divisor such that aL − (KX +∆) is nef and log big on (X,∆) for some a ∈ Z>0. Then |mL| is base point free for every m ≫ 0. 0. Introduction The purpose of this paper is to prove the following theorem. This type of base point freeness was suggested by M. Reid in [Re, 10.4]. Theorem 0.1 (Base point free theorem of Reid-Fukuda type). Assume that (X...
