Abstract:

In this talk we give new pinching phenomena of closed minimal Legendrian submanifolds in the unit sphere. Utilizing the maximum principle, we obtain a new characterization of the Calabi torus in the unit sphere which is the minimal Calabi product Legendrian immersion of a point and the totally geodesic Legendrian sphere. This is based on joint work with Prof. Linlin Sun and Dr. Jiabin Yin.
