On a Conjecture of Hacon and Mckernan in Dimension Three

چکیده
We prove that there exists a universal constant r3 such that if X is a smooth projective threefold overCwith non-negative Kodaira dimension, then the linear system |rKX | admits a fibration that is birational to the Iitaka fibration as soon as r ≥ r3 and sufficiently divisible. This gives an affirmative answer to a conjecture of Hacon and McKernan [5, Conjecture 1.7] in the case of threefolds.

$L_1$-Biharmonic Hypersurfaces in Euclidean Spaces with Three Distinct Principal Curvatures
Chen's biharmonic conjecture is well-known and stays open: The only biharmonic submanifolds of Euclidean spaces are the minimal ones. In this paper, we consider an advanced version of the conjecture, replacing $Delta$ by its extension, $L_1$-operator ($L_1$-conjecture). The $L_1$-conjecture states that any $L_1$-biharmonic Euclidean hypersurface is 1-minimal. We prove that the $L_1$-conje...
متن کاملA short proof of the maximum conjecture in CR dimension one
In this paper and by means of the extant results in the Tanaka theory, we present a very short proof in the specific case of CR dimension one for Beloshapka's maximum conjecture. Accordingly, we prove that each totally nondegenerate model of CR dimension one and length >= 3 has rigidity. As a result, we observe that the group of CR automorphisms associated with each of such models contains onl...
متن کاملJumping of the nef cone for Fano varieties
Among all projective algebraic varieties, Fano varieties (those with ample anticanonical bundle) can be considered the simplest. Birkar, Cascini, Hacon and McKernan showed that the Cox ring of a Fano variety, the ring of all sections of all line bundles, is finitely generated [4]. This implies a fundamental fact about the birational geometry of a Fano variety: there are only finitely many small...
متن کاملAn Informal Introduction to the Minimal Model Program
This is an expanded version of a talk given in the Fall 2007 Forschungsseminar at the Universität Duisburg-Essen. The purpose of our seminar was to understand the recent seminal work [2] of Hacon and McKernan. This note is written for non-specialists by a non-specialist, and hence might contain more or simply different details than experts would think necessary. Naturally, no claims regarding o...
متن کاملExtension of Sections via Adjoint Ideals Lawrence Ein and Mihnea Popa
We prove some extension theorems and applications, inspired by the very interesting recent results of Hacon-McKernan [HM1], [HM2] and Takayama [Ta], used in the minimal model program and in turn inspired by fundamental results of Siu. Parts of the proofs we give follow quite closely techniques in [Ka], [HM1], [HM2], and [Laz], which use asymptotic constructions. Some related analytic statements...
