In this note, we study the Atiyah class and Todd class of the DG manifolds $(F[1],d_F)$ coming from an integrable distribution $F \subset T_{\mathbb{K}} M$, where $T_{\mathbb{K}} M = TM$ when $\mathbb{K} = \mathbb{R}$ and $T_{\mathbb{K}} M = TM \otimes_{\mathbb{R}} \mathbb{C}$ when $\mathbb{K} = \mathbb{C}$. We show that these two classes are canonically identical to those of the Lie pair $(T_\mathbb{K} M, F)$. 查看全文>>
