In this talk, we will introduce a new proof for Toponogov's theorem (in the large) in Alexandrov geometry with lower curvature bound.The idea of the proof comes from the fact that, in Riemannian geometry, the sectional curvature can be seen from geodesic variations (i.e. the second variation formula). This is a joint work with HU Shengqi and SU Xiaole.
