通过将Lusztig在特征系数为0的情况下的各种结果推广到模集,构造了任意经典群的模广义施普林格对应。我们确定了所有经典类型的倒钩对,并显式地计算了具有任意特征系数的SL(n)和具有特征-2系数的SO(n)和Sp(2n)的对应关系。
We construct a modular generalized Springer correspondence for any classical group, by generalizing to the modular setting various results of Lusztig in the case of characteristic-0 coefficients. We determine the cuspidal pairs in all classical types, and compute the correspondence explicitly for SL(n) with coefficients of arbitrary characteristic and for SO(n) and Sp(2n) with characteristic-2 coefficients.
