报告摘要: The notion of flag curvature is a natural extension of sectional curvature. However, unlike sectional curvature in the Riemannian setting, flag curvature alone does not fully control the structure of a Finsler metric. Various non-Riemannian quantities also play essential roles. In this talk, I will discuss one of them—the so-called T-curvature—and its interaction with flag curvature.
