On the deformed Bott-Chern cohomology

Abstract

Given a compact complex manifold $X$ and a integrable Beltrami differential $\varphi \in A^{0,1}(X,T_X^{1,0})$, we introduce a double complex structure on $A^{\bullet ,\bullet }(X)$ naturally determined by $\varphi$ and study its Bott-Chern cohomology. In particular, we establish a deformation theory for Bott-Chern cohomology and use it to compute the deformed Bott-Chern cohomology for the Iwasawa manifold and the holomorphically parallelizable Nakamura manifold. The $\partial {\bar{\partial }}_{\varphi }$-lemma is studied and we show a compact complex manifold satisfying $\partial {\bar{\partial }}_{\varphi }$-lemma is formal.
