如果我们把时空连续统归结为一种微观结构,它可以用伪黎曼度规和独立的线性联系来几何描述。除了能量-动量之外,这种度规-仿射时空还可以携带次动量(广义自旋),其内在部分由流形诱导,即由仿射群GA(4,R)的无限分量表示诱导。
If we attribute to the spacetime continuum a microstructure, it can be geometri cally described by means of a pseudo-Riemannian metric and an independent linear connection. Besides energy-momentum, such a metric-afnne spacetime can carry hypennomentum (generalizing spin), the intrinsic part of which is induced by manifields, that is, by infinite-component representations of the affine group GA (4, R).
