Non-Vanishing Theorems for Rank 2 Bundles on P: a Simple Approach without the Speciality Lemma
نویسندگان
چکیده
The paper investigates vanishing conditions on the first cohomology module of a normalized rank 2 vector bundle F on P which force F to split. The present vanishing conditions improve other conditions known in the literature and are obtained with simple computations on the Euler characteristic function, avoiding the speciality lemma and other heavy tools.

Vanishing Theorems on Complete K Ahler Manifolds and Their Applications
Semi-positive line bundles over compact Kahler manifolds have been the focus of studies for decades. Among them, there are several straddling vanishing theorems such as the Kodaira-Nakano Vanishing Theorem, Vesentini-Gigante-Girbau Vanishing Theorems and KawamataViehweg Vanishing Theorem. As a corollary of the above mentioned vanishing theorems one can easily show that a line bundle over compa...
متن کاملGV-SHEAVES, FOURIER-MUKAI TRANSFORM, AND GENERIC VANISHING By GIUSEPPE PARESCHI and MIHNEA POPA
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 vanishin...
متن کاملVanishing Theorems and Universal Coverings of Projective Varieties
This article contains a new argument which proves vanishing of the first cohomology for negative vector bundles over a complex projective variety if the rank of the bundle is smaller than the dimension of the base. Similar argument is applied to the construction of holomorphic functions on the universal covering of the complex projective variety .

متن کاملProbing Moduli Spaces of Sheaves with Donaldson and Seiberg Witten Invariants
We use Donaldson invariants of regular surfaces with pg > 0 to make quantitative statements about modulispaces of stable rank 2 sheaves. We give two examples: a quantitative existence theorem for stable bundles, and a computation of the rank of the canonical holomorphic two forms on the moduli space. The results are in some sense dual to the Donaldson and O’Grady non vanishing theorems because ...
