在本文中,我们找到了表征局部投影平坦芬斯勒度量的方程,其形式为 F = (alpha + beta)(2)/alpha,其中 alpha = root a(ij)y(i)y(j) 是黎曼度量,beta = b(i)y(i) 是 1-形式。然后我们完全确定了那些具有恒定旗曲率的局部结构。
In this paper, we find equations that characterize locally projectively flat Finsler metrics in the form F = (alpha + beta)(2)/alpha, where alpha = root a(ij)y(i)y(j) is a Riemannian metric and beta = b(i)y(i) is a 1-form. Then we completely determine the local structure of those with constant flag curvature.
