Periodic symplectic and Hamiltonian diffeomorphisms on irrational ruled surfaces
Nicholas Lindsay, Weiyi Zhang
We investigate when finite-order Hamiltonian diffeomorphisms extend to Hamiltonian circle actions, probing the transition from discrete to continuous symmetry in symplectic topolog…
Images and singularity subsets of pseudoholomorphic maps
Weiyi Zhang
We study the image and the singularity subset of a general pseudoholomorphic map. We show that the image of a proper pseudoholomorphic map is a pseudoholomorphic subvariety when th…
Symplectic blowing down in dimension Six
Tian-Jun Li, Yongbin Ruan, Weiyi Zhang
We establish a blowing down criterion in the context of birational symplectic geometry in dimension 6.
Almost complex Hodge theory
Weiyi Zhang
We review the recent development of Hodge theory for almost complex manifolds. This includes the determination of whether the Hodge numbers defined by -Laplacian are…
Almost Kähler Kodaira-Spencer problem
Tom Holt, Weiyi Zhang
We show that the almost complex Hodge number varies with different choices of almost Kähler metrics. This answers the almost Kähler version of a question of Kodaira and S…
From Smooth to Almost Complex
Weiyi Zhang
This article mainly aims to overview the recent efforts on developing algebraic geometry for an arbitrary compact almost complex manifold. We review the results obtained by the gui…
