论文摘要
我们介绍了一个扭曲的$ \ Mathcal {d} $ - 在某个子变量等异态上的模块的类别中的排名一部分本地系统家庭,以$ {\ Mathbb {g} _ {\ text {\ text {m}}}}^2 $的$ \ text text text fext {sl sl} _2 $的affine标志的品种的品种。然后,我们就这些本地系统(即它们的参数)提供了一个标准,以便从$ \ Mathcal {d} $ - 模块的意义上清晰扩展。
We introduce a family of rank-one local systems in the category of twisted $\mathcal{D}$-modules on a certain subvariety isomorphic to ${\mathbb{G}_{\text{m}}}^2$ of the affine flag variety of $\text{SL}_2$. We then give a criterion for these local systems, in terms of their parameters, to extend cleanly in the sense of $\mathcal{D}$-modules.
