1) (G-)semisymmetric (G-)半对称 2) semisymmetric G-半对称图 1. A regular G- edge-transtive but not G-vertex-transtive graph will be referred to as a G-semisymmetricgraph. 特别地,若G=AutX这时的G-点传递图、G-边传递图、(G-)半对称图称为点传递图,边传递图,半对称图。
为什么我用半对称翼型..为什么我用半对称翼型(semi-symmetric)飞的还没平底翼(falt bottom)快,半对称翼型要慢不少,而平底翼速度顶的很快理论上不是半对称阻力更小吗,这为什么反过来了
1) semi-symmetric recurrent connection 半对称循环联络 1. In this paper we studysemi-symmetric recurrent connections and obtain the expression of thesemi-symmetric recurrent connection. 半对称度量联络的基本性质是它的共形曲率张量与黎曼联络的Weyl共形曲率张量相等,本文研究半对称循环联络,并导出此联络的表达式...
said to be semi-symmetric connection if there is a non-zero vec-tor f i eld C ∈ X( f M) such that its torsion T satisf i es the identity(1)eT(X,Y ) = ˜ g(C,Y )X − ˜ g(C,X)Y, X,Y ∈ X( f M).If in additione∇˜ g = 0, the connectione∇ is ...
The class of semisymmetric graphs was first introduced by Folkman [13], where several infinite families of such graphs were constructed and eight open problems were posed which spurred the interest in this topic (see for example [4,5,17,20,24]). By using group-theoretic methods, Iofinova ...
