On projectively flat Kropina metrics
Xiaoling Zhang, Yibing Shen
In this paper, a characteristic condition of the projectively flat Kropina metric is given. By it, we prove that a Kropina metric with constant curvature and $\|β\|_α…
On Einstein Kropina metrics
Xiaoling Zhang, Yi-Bing Shen
In this paper, a characteristic condition of Einstein Kropina metrics is given. By the characteristic condition, we prove that a non-Riemannian Kropina metric with…
On Einstein Matsumoto metrics
Yi-Bing Shen, Xiaoling Zhang
In this paper, the necessary and sufficient conditions for Matsumoto metrics to be Einstein are given. It is shown that if the length of with respect to …
Connectivity and Minimal Distance Spectral Radius of Graphs
Xiaoling Zhang, Chris Godsil
In this paper, we study how the distance spectral radius behaves when the graph is perturbed by grafting edges. As applications, we also determine the graph with cut vertices (…
