Sharp degree bound for rational proper maps from to

Tianzhi Hu, Mai Shi, Pingsan Yuan

We prove D'Angelo's degree conjecture for rational proper holomorphic maps from to , establishing the sharp degree bound of five. Suppose, to the contr…

Isomonodromic deformations of Higgs bundles and characterization of the non-abelian Noether--Lefschetz locus

Tianzhi Hu, Ruiran Sun, Jinbang Yang +1

Let be a smooth proper family of smooth projective varieties. An irreducible complex local system on a fiber admits an isomonodromic deformation, hence determines a holo…

Higher order isomonodromic deformation of Higgs bundles and a characterization of the non-abelian Noether-Lefschetz locus

Tianzhi Hu, Ruiran Sun, Jinbang Yang +1

The purpose of this paper is to establish a local theory of the non-abelian Noether--Lefschetz locus. Given a family of projective manifolds over a complex variety , the isomono…

Non-Abelian Kodaira-Spencer Map and non-existence of holomorphic isomonodromic deformation of Higgs bundles over Teichmüller spaces

Tianzhi Hu, Ruiran Sun, Kang Zuo

We define the isomonodromic deformation of a Higgs bundle on a compact Riemann surface via the Hitchin--Simpson correspondence and the isomonodromic deformation of the associated l…

Kodaira-Spencer Map on the Hitchin-Simpson Correspondence

Tianzhi Hu, Ruiran Sun, Kang Zuo

We define the isomonodromic deformation of a Higgs bundle over a compact Riemann surface via the Hitchin-Simpson correspondence and the isomonodromic deformation of a local system.…

On the distribution of non-rigid families in the moduli spaces

Ke Chen, Tianzhi Hu, Ruiran Sun +1

This paper investigates the distribution of non-rigid families in a moduli space of polarized projective manifolds for which the infinitesimal Torelli theorem holds.…
