摘要
研究了具有相对迷向平均Landsberg曲率的Matsumoto度量F=2α/(α-β),其中α=aijy^iy^j^(1/2)为黎曼度量,β=biyi为1-形式.特别给出Matsumoto度量具有相对迷向平均Landsberg曲率的几个等价条件.
In this paper, we study Matsumoto metric F =α^2/（α-β ）with relatively isotropic mean Lands b i berg curvature, where α=√αijy^iy^j is a Riemannian metric, amd β=biy^i is a 1-form. Several equivalent conditions under which Matsumoto metric is of relatively isotropic mean Landsberg curvature are given.
