Projective klt pairs with nef anti-canonical divisor

Frédéric Campana, Junyan Cao, Shin-ichi Matsumura

In this paper, we study a projective klt pair $(X, Δ)$ with the nef anti-log canonical divisor $- (K_{X} + Δ)$ and its maximally rationally connected fibration $ψ : X ⇢ Y$ .…

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 $X$ with pseudo-effect…
