我们考虑平坦D[公式:见正文]-膜横向探测Calabi-Yau流形的世界体积理论的全纯扭曲。用BV形式构造的链形复形计算了全纯扭曲理论中的局域可观测量。推广前面的[公式:见正文]中的工作,我们发现这个复合体可以与与Calabi-Yau相关的Ginzburg dg代数相联系。然而,这种识别是微妙的;这个复合体是促成自由理论的全纯扭曲的场的空间,它的差异来自于相互作用。对于[公式:见正文],这个全纯扭曲理论与椭圆亏格有关。我们给出了探索Calabi-Yau四重奇点的D_1膜和箭图规范理论的一般描述。此外,我们还提出了大对称乘积的等变Hirzebruch亏格与循环同调之间的关系。
We consider the holomorphic twist of the worldvolume theory of flat D[Formula: see text]-branes transversely probing a Calabi–Yau manifold. A chain complex, constructed using the BV formalism, computes the local observables in the holomorphically twisted theory. Generalizing earlier work in the case [Formula: see text], we find that this complex can be identified with the Ginzburg dg algebra associated to the Calabi–Yau. However, the identification is subtle; the complex is the space of fields contributing to the holomorphic twist of the free theory, and its differential arises from interactions. For [Formula: see text], this holomorphically twisted theory is related to the elliptic genus. We give a general description for D1-branes probing a Calabi–Yau fourfold singularity, and for [Formula: see text] quiver gauge theories. In addition, we propose a relation between the equivariant Hirzebruch [Formula: see text] genus of large-[Formula: see text] symmetric products and cyclic homology.
