Obstructions of deforming complex structures and cohomology contractions
Xueyuan Wan, Wei Xia
The Kodaira principle asserts that suitable cohomological contraction maps annihilate obstructions to deforming complex structures. In this paper, we revisit these phenomena from a…

Kähler metrics of negative holomorphic (bi)sectional curvature on a compact relative Kähler fibration
Xueyuan Wan
For a compact relative Kähler fibration over a compact Kähler manifold with negative holomorphic sectional curvature, if the relative Kähler form on each fiber also exhibits negati…
