1) Pontrjagin characteristic form
Pontrjagin示性式
2) characteristic forms
示性式
1.
In the paper [1], we gave the integral formula of the general characteristic forms of a Riemannian manifold.
在[1]中,我们给出了一个黎曼流形的一般示性式的积分公式。
3) Euler characteristic form
Euler示性式
1.
We shall show that the Euler characteristic form of E plays the roleof the Stiefel-Whitney characteristic form of M, and the integral formula of the Eulercharacteristic form of E is just the generalized Gauss-Bonnet formula.
我们将指出:矢丛E的Euler示性式扮演了流形M的Stiefel-Whitney示性式的角色,不过这个示性式积分时必须mod。
4) Pontrjagin spaces
Pontrjagin空间
1.
We show that the Putnam-Puglede theorem holds, if the normal operator A on the Pontrjagin spaces has not a neutral invariant subspace.
证明了:当Pontrjagin空间上的正规算子A没有零性不变子空间时,Putnam- Fuglede定理成立;当正规算子A有零性不变子空问时,通过构造反例说明此时Putnam- Fuglede定理不成立,并对Π1空间上算子相关的交换性条件进行了讨论,得到了Π1空间上算子代数的二次交换定理。
2.
In this paper, problems of conditional positive forms and dilations are studied, and dilation theorems of symmetric operator on Pontrjagin spaces are obtained.
得到了Pontrjagin空间上对称算子的扩张定理。
