余辛流形及其不变子流形

Invariant Submanifold of A Cosymplectic Manifold

介绍了一类重要的流形——余辛流形,给出了关于余辛流形曲率的一些关系式,并研究了余辛流形的不变子流形,得到了一些有趣的性质:余辛流形的不变子流形仍然是余辛流形,并且是最小子流形.

A class important manifold-cosymplectic manifold is introduced, and the invariant submanifold of cosymplectic manifold is studied to obtain some interesting properties of the invariant submanifolds. The invariant submanifold of the cosymplectic manifold is still a cosymplectic manifold and a minimal submanifold.
