Let g be a restricted Lie superalgebra of Cartan type W(n), S(n)or H(n) over an algebraically closed field k of prime characteristic p > 3, in the sense of modular version of Kac’s definition in 1977. In this note, we show that the restricted representation category over g has only one block (reckoning parities in). This phenomenon is very different from the case of characteristic zero.

Cartan型李超代数的受限表示中的块

设 g 是一个 Cartan 型 W(n)、S(n) 或 H(n) 的受限李超代数,在一个质特征 p > 3 的代数闭域 k 上,在 Kac 1977 年定义的模版本的意义上。在这一点上,我们表明 g 上的受限表示类别只有一个块(计算奇偶校验)。这种现象与特征零的情况非常不同。
