symmetric operator

In chapter 2, we give the classification concept of degenerate operator algebras on the nk spaces by symmetric ideals, and show that thus operator algebra consists of six classes.

第二章利用对称理想给出∏k空间上退化算子代数分类的概念。说明∏k空间上退化算子代数分为六类。

STUDYING TO SUPER-SYMMETRIC ALGEBRA GSU_2 ⅱ. Racah Coefficient and irreducible tensor operator

超对称代数GSU2的研究Ⅱ.Racah系数和不可约张量算符

We consider the operator algebras on the Pontrjagin spaces, and study the classification problem of degenerate operator algebras, the derivations problem of operator algebras, and the symmetric problem of ideals in operator algebras.

本文考虑Pontrjagin空间上的算子代数。讨论了退化算子代数的分类问题；算子代数理想的对称性问题；算子代数的导子问题以及算子代数的交换性问题。

In this paper, we study complete space-like hypersurfaces with constant normal scalar curvature in a locally symmetric Lorentz space satisfying some curvature conditions. With the operator L_1 introduced by Cheng S Y and Yau S T, a classified theorem is obtained.

讨论了在局部对称Lorentz空间中的具有常标准数量曲率的满足一定曲率条件的完备类空超曲面，利用Cheng S Y和Yau S T介绍的自伴随算子L1，得到了一个分类定理。
