摘要:Minimal submanifolds have been widely studied. Many interesting pinching theorems for minimal submanifolds in a sphere or a Euclidean space have been proven. However, similar results for minimal submanifolds in a hyperbolic space are yet to be found. We prove for the first time gap theorems on the square norm of the second fundamental form of complete minimal submanifolds in a hyperbolic space. We also obtain one end theorem for them.
