- Any symmetric space corresponds to a Lie group and an involution of it.The associated twisted conjugate action is related to the involution. 每個對稱空間對應著一個李群及這個李群的一個對合自同構,相應的扭共軛作用與這個對合自同構有關。
- In this paper, the conclusion is that the intersection of lie subring of a Lie group is a Lie subring is obtained, moreover,it gives the Lie algebra of the Lie subring. 文章通過李子群的性質得出了李群的兩個李子群的交依然是李子群的結論,進而得出這一李子群的李代數形式。
- In this paper,by giving a left invariant and symplectic structure, we have discussed the left invariant vector field and Maurer-Cartan form on Lie group,and have drawn some conclusions on them. 文章通過對李群上賦予一個左不變的辛結構,對李群上的左不變向量場及左不變1一形式進行研究,得出相關結論。
- First, it is shown from a new viewpoint that the universal enveloping algebra generates a Lie subgroup of a known classical infinite dimensional Lie group, therefore the enlargability is ensured. 首先,本文從一個新的視角證明泛包絡代數作為無窮維李代數生成一個標準無窮維李群的子李群,從而保證了泛包絡代數的可擴張性;
- On a table with a green cover lay a number of open books, and before the table stood a massive armchair with a red velvet cushion. 一張鋪著綠色檯布的桌子上放著幾本打開的書,桌前擺著一把笨重的扶手椅,椅子上有一隻紅色天鵝絨的靠墊。

- But twisted conjugate actions of Lie groups have closed relation with nonabelian cohomology of cyclic groups with coefficients in Lie groups. 而李群的扭共軛作用與循環群以李群為係數的非交換上同調有非常密切的關係。
- And if we apply the same property to the identity automorphism, we get the closedness theorem for conjugacy classes of finite order in Lie groups. 而把同樣的性質應用到恆同自同構,我們會得到李群中有限階共軛類的閉性定理。
