Answers to three problems in Dinh-Sibony's list on holomorphic foliation theory

Zhangchi Chen

We address Problems~2.2(i), 2.2(ii), and~2.4 in Dinh--Sibony's list. For a saturated holomorphic curve foliation on a compact Kähler manifold with finitely many singularities, ever…

Conditional Oka Complex Structures of the Six-Sphere

Zhangchi Chen

Alpöge's construction produces a period family of compact complex threefolds fibred over , with complex two-tori as general fibres. We give a direct proof that every…

Nakano-positive determinants outside the Hodge-Riemann cone

Zhangchi Chen

Dinh and Nguyên asked whether the determinant of a Griffiths positive matrix of -forms belongs to the Hodge--Riemann cone. For every and $2\leqslant k\leqslant…
