摘要 研究Finsler度量中一类非常重要的几何量——推广的Douglas-Weyl度量.得到了n维(n≥3)流形上的Finsler度量是具有弱迷向旗曲率的推广的Douglas-Weyl度量的充分必要条件. We study a very important geometric quantity, Generalized Douglas-Weyl curvature and obtain a sufficient and neccessary condition for a Finsler metric on an n-dimension manifold (n≥3) to he a generalized Douglas-Weyl metric with weakly isotropic flag curvature.
