Almost nef regular foliations and Fujita's decomposition of reflexive sheaves
Masataka Iwai
In this paper, we study almost nef regular foliations. We give a structure theorem of a smooth projective variety with an almost nef regular foliation : admits…
On asymptotic base loci of relative anti-canonical divisors of algebraic fiber spaces
Sho Ejiri, Masataka Iwai, Shin-ichi Matsumura
In this paper, we study the relative anti-canonical divisor of an algebraic fiber space , and we reveal relations among positivity conditions of ,…
On projective manifolds with pseudo-effective tangent bundle
Genki Hosono, Masataka Iwai, Shin-ichi Matsumura
In this paper, we develop the theory of singular hermitian metrics on vector bundles. As an application, we give a structure theorem of a projective manifold with pseudo-effect…
Characterization of pseudo-effective vector bundles by singular Hermitian metrics
Masataka Iwai
In this paper, we give complex geometric descriptions of the notions of algebraic geometric positivity of vector bundles and torsion-free coherent sheaves, such as nef, big, pseudo…
Nadel-Nakano vanishing theorems of vector bundles with singular Hermitian metrics
Masataka Iwai
We study a singular Hermitian metric of a vector bundle. First, we prove the sheaf of locally square integrable holomorphic sections of a vector bundle with a singular Hermitian me…
