论文摘要
我们证明了Graber-Pandharipande的虚拟本地化定理的类似物，在$ \ text {sl} _2 $中，圆环的归一化器设置了一个动作，并由Chow组取代了一个适当扭曲的Witt组的共同体。
We prove an analog of the virtual localization theorem of Graber-Pandharipande, in the setting of an action by the normalizer of the torus in $\text{SL}_2$, and with the Chow groups replaced by the cohomology of a suitably twisted sheaf of Witt groups.
