我们引入了一个自然映射,从纯型复微分形式的空间上的复流形的无穷小变形的相应的。利用这一映射,我们推广了K. Liu,X.杨和第一作者。作为直接推论,我们证明了Hodge数的几个变形不变性定理。此外,我们还研究了在Kähler情形下的Gauduchon锥及其与平衡锥的关系,证明了Gauduchon锥在D.在Kählerian家族中,Popovici对于一种通用纤维的描述包含在该纤维的Gauduchon锥的封闭中。
We introduce a natural map from the space of pure-type complex differential forms on a complex manifold to the corresponding one on the infinitesimal deformations of this complex manifold. By use of this map, we generalize an extension formula in a recent work of K. Liu, X. Yang, and the first author. As direct corollaries, we prove several deformation invariance theorems for Hodge numbers. Moreover, we also study the Gauduchon cone and its relation with the balanced cone in the Kähler case, and show that the limit of the Gauduchon cone in the sense of D. Popovici for a generic fiber in a Kählerian family is contained in the closure of the Gauduchon cone for this fiber.
