We studied the global differential geometry of Riemannian manifolds and submanifolds including minimal submanifolds, constant mean curvature submanifolds, complex submanifolds and symplectic submanifolds, etc..

Since the early work of Gauss and Riemann, differential geometry has grown into a vast network of ideas and approaches, encompassing local considerations such as differential invariants and jets as well as global ideas, such as Morse theory and characteristic classes.
