Beauville--Bogomolov--Yau decomposition for Kähler generalized pairs

Shin-ichi Matsumura, Juanyong Wang, Xiaojun Wu +1

In this paper, we establish the Beauville--Bogomolov--Yau decomposition for generalized pairs in the Kähler setting, thereby extending this structure theorem to the natural framewo…

On compact Kähler manifolds with pseudo-effective tangent bundle

Shin-ichi Matsumura, Chenghao Qing

In this paper, we prove that a compact Kähler manifold $X$ with pseudo-effective (resp. singular positively curved) tangent bundle admits a smooth (resp. locally constant) rational…

Fundamental groups of compact Kähler manifolds with semi-positive holomorphic sectional curvature

Shin-ichi Matsumura

In this paper, we prove that a compact Kähler manifold $X$ with semi-positive holomorphic sectional curvature admits a locally trivial fibration $ϕ : X \to Y$ , where the fiber…
