摘要

让 $X$ 是由仿射代数群 $G$ 作用于 $\mathbb{C}$ 的仿射、光滑和诺特方案。应用$\href{https://doi.org/10.48550/arXiv.1807.03266}{[3, }\href{ https://doi.org/10.48550/arXiv.1812.03583}{4]}$ 中开发的技术,我们定义了一个在$X$上微分形式$\Omega_X$的dg-模块的派生类的dg-模型,这个派生类等价于派生群方案$(G, \Omega_G)$的作用。我们将得到的 dg 类与 $\href{https://doi.org/10.48550/arXiv.1510.07472}{[2]}$ 中考虑的、由 $T^\ast X$ 的派生哈密顿还原上的相干剪切给出的 dg 类进行比较。

Equivariant sheaves on loop spaces
Let $X$ be an affine, smooth, and Noetherian scheme over $\mathbb{C}$ acted on by an affine algebraic group $G$. Applying the technique developed in $\href{https://doi.org/10.48550/arXiv.1807.03266}{[3, }\href{ https://doi.org/10.48550/arXiv.1812.03583}{4]}$, we define a dg‑model for the derived category of dg‑modules over the dg‑algebra of differential forms $\Omega_X$ on $X$ equivariant with respect to the action of a derived group scheme $(G, \Omega_G)$. We compare the obtained dg‑category with the one considered in $\href{https://doi.org/10.48550/arXiv.1510.07472}{[2]}$ given by coherent sheaves on the derived Hamiltonian reduction of $T^\ast X$.
