摘要
We deal with a CR-submanifold M of a para-K%26#228;hlerian manifold M%26#732;, which carries a J-skew-symmetric vector field X. It is shown that X defines a global Hamiltonian of the symplectic form %26#937; on M%26#8868; and JX is a relative infinitesimal automorphism of %26#937;. Other geometric properties are given.
