Korea Institute for Advanced Study(韩国高等研究院)

AI总结:

该研究计算了振幅为$+1$的DG流形的Atiyah类,证明其消失等价于截面与零截面为干净相交,并将结果应用于编码两光滑流形导出相交的DG流形的Atiyah类研究。

摘要:

振幅为$+1$的DG流形编码了向量丛$E$的截面$s$与零截面的导出相交。本文计算了振幅为$+1$的DG流形的Atiyah类。特别地,我们证明了Atiyah类消失当且仅当$s$与零截面的相交是干净相交。作为应用,我们研究了编码两个光滑流形导出相交的DG流形的Atiyah类。

英文摘要:

A DG manifold of amplitude $+1$ encodes the derived intersection of a section $s$ and the zero section of a vector bundle $E$. In this paper, we compute the Atiyah class of DG manifolds of amplitude $+1$. In particular, we show that the Atiyah class vanishes if and only if the intersection of $s$ with the zero section is a clean intersection. As an application, we study the Atiyah class of DG manifolds that encodes the derived intersection of two smooth manifolds.
