An ampleness criterion with the extendability of singular positive metrics

Shin-ichi Matsumura

Coman, Guedj and Zeriahi proved that, for an ample line bundle $L$ on a projective manifold $X$ , any singular positive metric on the line bundle $L ∣_{V}$ along a subvariety $V \sub…

Asymptotic cohomology vanishing and a converse to the Andreotti-Grauert theorem on surfaces

Shin-ichi Matsumura

In this paper, we study relations between positivity of the curvature and the asymptotic behavior of the higher cohomology group for tensor powers of a holomorphic line bundle. The…
