Asymptotic estimate of cohomology groups valued in pseudo-effective line bundles

Abstract

In this paper, we study questions of Demailly and Matsumura on the asymptotic behavior of dimensions of cohomology groups for high tensor powers of (nef) pseudo-effective line bundles over non-necessarily projective algebraic manifolds. By generalizing Siu's ∂∂-formula and Berndtsson's eigenvalue estimate of ∂-Laplacian and combining Bonavero's technique, we obtain the following result: given a holomorphic pseudo-effective line bundle (L, hL) on a compact Hermitian manifold (X,ω), if hL is a singular metric with algebraic singularities, then Hq(X,Lk E I(hLk))≤ Ckn-q for k large, with E an arbitrary holomorphic vector bundle. As applications, we obtain partial solutions to the questions of Demailly and Matsumura.
