非线性联络论、Beltrami联络与二维引力

NONLINEAR CONNECTION, BELTRAMI CONNECTION AND TWO-DIMENSION GRAVITY

本文利用非线性联络的理论,在二维空间中提出Beltrami联络的概念,用这一概念讨论二维Polyakov引力的对称性。

In terms of the theory of nonlinear connection, we proposed the concept of Beltrami connection in two dimension space, and discussed the symmety of Polyakov's two dimension gravty.
