Base Point Free Theorems —saturation, B-divisors, and Canonical Bundle Formula—
We reformulate the Kawamata-Shokurov base point free theorem by using the notion of b-divisors and saturation of linear systems, which was introduced by Shokurov. Combining the refined Kawamata-Shokurov base point free theorem with Ambro’s canonical bundle formula, we quickly reprove the main theorem of Kawamata’s paper: Pluricanonical systems on minimal algebraic varieties, without using the n...
متن کاملA Canonical Bundle Formula
A higher dimensional analogue of Kodaira's canonical bundle formula is obtained. As applications, we prove that the logcanonical ring of a klt pair with 3 is nitely generated, and that there exists an e ectively computable natural numberM such that jMK X j induces the Iitaka bering for every algebraic threefold X with Kodaira dimension = 1.
متن کاملHigher Direct Images of Log Canonical Divisors and Positivity Theorems
In this paper, we investigate higher direct images of log canonical divisors. After we reformulate Koll ar's torsion-free theorem, we treat the relationship between higher direct images of log canonical divisors and the canonical extensions of Hodge ltration of gradedly polarized variations of mixed Hodge structures. As a corollary, we obtain a logarithmic version of Fujita-Kawamata's semi-posi...
متن کاملA Canonical Bundle Formula for Projective Lagrangian Fibrations
We classify singular fibres of a projective Lagrangian fibration over codimension one points. As an application, we obtain a canonical bundle formula for a projective Lagrangian fibration over a smooth manifold.
متن کاملON b-FUNCTIONS OF LINEAR FREE DIVISORS
We describe b-functions of linear free divisors and use these results to prove that the logarithmic comparison theorem holds for Koszul free reductive linear free divisors exactly if they are (strongly) Euler homogeneous.
