摘要:本文主要研究了双挠积 Finsler 度量的平均 Berwald 曲率和迷向平均 Berwald 曲率，给出了双 挠积 Finsler 度量是弱 Berwald 度量的充要条件，证明了在一定条件下具有迷向平均 Berwald 曲率的双挠积 Finsler 度量是弱 Berwald 度量。
Abstract:This paper mainly studies the mean Berwald curvature and isotropic mean Berwald curvature doubly-twisted product of Finsler metrics. The necessary and sufficient conditions for the doubly-twisted product of Finsler metrics are weakly Berwald metrics. It is proved that under certain conditions the doubly-twisted product of Finsler metrics with isotropic mean Berwald curvature is weakly Berwald metrics.
