On Riemann curvature of singular square metrics
Changtao Yu
Square metrics is an important class of Finsler metrics. Recently, we introduced a special class of non-regular Finsler metrics called singular square metrics. The main purpose of…
Some remarks on Einstein-Randers metrics
Xiaoyun Tang, Changtao Yu
In this essay, we study the sufficient and necessary conditions for a Randers metrc to be of constant Ricci curvature without the restriction of strong convexity (regularity). The…
Projectively flat general -metrics with constant flag curvature
Changtao Yu, Hongmei Zhu
In this paper we study the flag curvature of a particular class of Finsler metrics called general -metrics, which are defined by a Riemannian metric and a -form .…
On Einstein square metrics
Zhongmin Shen, Changtao Yu
In this paper, we study an important class of Finsler metrics--square metrics. We give two expressions of such metrics in terms of a Riemannian metric and a 1-form. We show that Ei…
On a new class of Finsler metrics
Changtao Yu, Hongmei Zhu
In this paper, the geometric meaning of (alpha,beta)-norms is made clear. On this basis, we introduce a new class of Finsler metrics called general (alpha,beta)-metrics, which are…
