报告摘要：It is a well-known result of Clemens-often referred to as Kodaira's principle-that on a compact Kähler manifold the obstruction classes to deforming the complex structure are annihilated by contraction with Dolbeault cohomology classes. We will consider some generalizations of this result to non-K\ahler manifolds. In particular, we show the obstructions of deforming complex structures is related to deformations of filtered forms. This is a joint work with Xueyuan Wan.
