Title: Calabi-Yau theorem and almost complex deformations

Speaker: Dr. Weiyi Zhang, University of Minnesota

Abstract:
Motivated by Donaldson's paper "Two-forms on four-manifolds and elliptic equations", we talk about the some properties of the space of (1,1) cohomology class for an almost complex 4-manifold. We will also study the properties of the space under the deformation of the almost complex structures.
