摘要:

该文在(0, n) 的维辛超流形M=(e, A) 的左A 模DerA上定义了算子η, 给出了M上的向量场为辛向量场的两个充要条件, 并得到了算子η的一些恒等式. 此外,  还给了余切超流形T*(M)=(e, S(DerA))上辛向量场的三个判定条件, 并证明了它们的等价性.

关键词: (0, n) 维辛超流形, 余切超流形T*(M)=(e, S(DerA)),  , 算子η, 辛向量场

Abstract:

In this paper, an operator η is defined in the left A module DerA on symplectic supermanifoldM = (e, A) of dimension (0, n). Two sufficient and necessary conditions are given for vector fields on M being symplectic vecter fields, and some identities about the operator η are obtianed. Furthermore, three decision conditions are given to judge symplectic vector fields on cotangent supermanifold T*(M) = (e, S(DerA)), and their equivalences are proved.

Key words: Symplectic supermanifold of dimension (0, n), Cotangent supermanifold T* (M) =(e, S(DerA)), Operator η, Symplectic vecter field.
