摘要
设 G 是定义在奇特征有限域上的交点群或正交群，设 D ≤ G 是一个 Sylow 2 子群。在本文中，我们对本质 2 子群进行了分类，并确定了弗罗贝尼斯范畴ℱD(G) 的本质 2 级。这与安-迪特里希和曹-安-曾的结果一起，完成了经典群的本质子群和本质秩的工作。
Let G be a symplectic or orthogonal group defined over a finite field with odd characteristic and let D ≤ G be a Sylow 2-subgroup. In this paper, we classify the essential 2-subgroups and determine the essential 2-rank of the Frobenius category ℱD(G). Together with the results of An-Dietrich and Cao–An–Zeng, this completes the work of essential subgroups and essential ranks of classical groups.
期刊介绍：
Acta Mathematica Sinica, established by the Chinese Mathematical Society in 1936, is the first and the best mathematical journal in China. In 1985, Acta Mathematica Sinica is divided into English Series and Chinese Series. The English Series is a monthly journal, publishing significant research papers from all branches of pure and applied mathematics. It provides authoritative reviews of current developments in mathematical research. Contributions are invited from researchers from all over the world.
