摘要 利用广义极大值原理和自伴随微分算子研究四元数射影空间中常数量曲率完备全实伪脐子流形的Pinching问题,得到了两个该流形成为全测地或全脐的刚性定理. The authors studied the Pinching problem on submanifolds with constant scalar curvature in a quaternion projective space by means of the generalized maximal principle and self-adjoint differential operator,and obtained two rigidity theorems for submanifolds to be totally geodesic or totally umblilic.
