Witt型李超代数的极大根阶化子代数
Maximal root-graded subalgebras of Witt Lie superalgebras
【摘要】 设W(m,n)是特征p>3的代数闭域上有限维Witt型李超代数.证明了W(m,n)的极大根阶化子代数一定是其极大Z-阶化子代数,从而刻画了W(m,n)的所有极大根阶化子代数.结果有助于理解Witt型李超代数W(m,n)的内在性质.
【Abstract】 Let W(m, n) be the finite dimensional Witt Lie superalgebras over algebraically closed fields of characteristic p >3. We prove that maxmimal root-graded subalgebras of W(m, n) are maximal Z-graded subalgebras of W(m, n). Then we characterize all maximal root-graded subalgebras of W(m, n). It is helpful to further understand the intrinsic properties of Witt Lie superalgebras W(m, n).
