Weak Quadruple Comparison and Structure Theory Beyond Alexandrov Geometry
Bang-Xian Han, Liming Yin
We introduce a new four-point comparison principle, called the -weak quadruple condition, for non-Riemannian spaces with synthetic non-negative curvature. This con…

A class of Randers metrics of scalar flag curvature
Xinyue Cheng, Li Yin, Tingting Li
One of the most important problems in Finsler geometry is to classify Finsler metrics of scalar flag curvature. In this paper, we study the classification problem of Randers metric…
