Yukinobu Toda

AI总结:

本文证明解析锥上范畴化 DT 不变量的穿墙公式,以范畴化 Hall 乘积刻画半正交分解,并进一步推出范畴化 PT 稳定对不变量的分解。

摘要:

我们证明了解析锥上范畴化 Donaldson–Thomas 不变量的穿墙公式,该公式将其上数值 DT 不变量的 Nagao–Nakajima 穿墙公式进行了范畴化。范畴化 Hall 乘积被用于将穿墙公式描述为半正交分解。连续应用范畴化穿墙公式,可得到解析锥上范畴化 Pandharipande–Thomas 稳定对不变量的半正交分解;这些分解将其上数值 PT 不变量生成级数的乘积展开公式予以范畴化。

英文摘要:

We prove wall-crossing formula for categorical Donaldson-Thomas invariants on the resolved conifold, which categorifies Nagao-Nakajima wall-crossing formula for numerical DT invariants on it. The categorified Hall products are used to describe the wall-crossing formula as semiorthogonal decompositions. A successive application of categorical wall-crossing formula yields semiorthogonal decompositions of categorical Pandharipande-Thomas stable pair invariants on the resolved conifold, which categorify the product expansion formula of the generating series of numerical PT invariants on it.
