We give a new Tian–Todorov lemma on deformations of CR-structures and use it to reprove the deformation unobstructedness of normal compact strongly pseudoconvex CR-manifold under the assumption of $$d'd''$$ d ′ d ′ ′ -lemma, more faithfully following Tian–Todorov’s approach.

关于 Tian-Todorov 引理及其在 CR 结构变形中的应用

我们给出了一个新的关于 CR-结构变形的 Tian-Todorov 引理,并用它来证明在 $$d'd''$$d ' d ' ' -lemma 假设下正态紧致强赝凸 CR-流形的变形无障碍性,更忠实地遵循田-托多罗夫的方法。
