GV-SHEAVES, FOURIER-MUKAI TRANSFORM, AND GENERIC VANISHING By GIUSEPPE PARESCHI and MIHNEA POPA

چکیده
We prove a formal criterion for generic vanishing, in the sense originated by Green and Lazarsfeld and pursued further by Hacon, but in the context of an arbitrary Fourier-Mukai correspondence. For smooth projective varieties we apply this to deduce a Kodaira-type generic vanishing theorem for adjoint bundles associated to nef line bundles, and in fact a more general generic Nadel-type vanishing theorem for multiplier ideal sheaves. Still in the context of the Picard variety, the same method gives various other generic vanishing results, by reduction to standard vanishing theorems. We further use our criterion in order to address some examples related to generic vanishing on higher rank moduli spaces.

Gv-sheaves, Fourier-mukai Transform, and Generic Vanishing
In this paper we use homological techniques to establish a general approach to generic vanishing theorems, a subject originated with the pioneering work of Green-Lazarsfeld [GL1] and [GL2]. Our work is inspired by a recent paper of Hacon [Hac]. Roughly speaking, we systematically investigate – in a general setting – the relation between three concepts: (1) generic vanishing of (hyper-)cohomolog...
متن کاملHodge modules on complex tori and generic vanishing for compact Kähler manifolds
The term “generic vanishing” refers to a collection of theorems about the cohomology of line bundles with trivial first Chern class. The first results of this type were obtained by Green and Lazarsfeld in the late 1980s [13, 14]; they were proved using classical Hodge theory and are therefore valid on arbitrary compact Kähler manifolds. About ten years ago, Hacon [15] found a more algebraic app...
متن کاملGeneric Vanishing Theory via Mixed Hodge Modules
We extend most of the results of generic vanishing theory to bundles of holomorphic forms and rank-one local systems, and more generally to certain coherent sheaves of Hodge-theoretic origin associated with irregular varieties. Our main tools are Saito’s mixed Hodge modules, the Fourier–Mukai transform for D-modules on abelian varieties introduced by Laumon and Rothstein, and Simpson’s harmonic...
متن کاملSome Basic Results on Irregular Varieties Revisited with the Fourier-mukai Transform
Recently Fourier-Mukai methods have proved to be a valuable tool in the study of the geometry of irregular varieties. An especially interesting point is the interplay between the generic vanishing theorems of Green and Lazarsfeld and the notion of generic vanishing sheaves, naturally arising in the Fourier-Mukai context. The purpose of this mainly expository paper is to exemplify this circle of...
متن کامل3 Generic Vanishing , Gaussian Maps , and Fourier - Mukai Transform
A quite basic fact about abelian varieties (and complex tori) is that the only line bundle in Pic 0 with non-trivial cohomology is the structure sheaf. Mumford, in his treatment of the dual abelian variety, made the far-reaching remark that this yields the following sheaf-theoretic formulation. Let A be an abelian variety (over an algebraically closed field) of dimension g, let us denote A = Pi...
