  • 通过引入二重复对称度规张量,建立了一种二重复对称引力理论. 从一个二重实的作用量出发,导出了静态球对称二重复度规的具体表达式. 该理论扩展了Moffat结果,不仅自然地得到了双曲复对称引力理 论,而且把著名的Schwarzschild解作为特殊情况包含在其中,并且在线性化的弱场近似下自动摆脱了Moffat理论中存在的负 能鬼态问题. 进一步,通过将二重复坐标推广到满足二重非对易关系以及将Moyal星积二重 化,由此构造出二重非交换复对称引力场作用量.

     

    In this paper,the double complex symmetric gravitational theory is established and the concrete expression of the static spherically symmetric double complex metrics is derived by introducing the double complex symmetric metric tensors. In this theory the Moffat's results are extended,the hyperbolic complex symmetric gravitational theory is naturally obtained and the famous Schwarzchild solution is contained as the special case. Moreover,in the linearized weak field approximation the hyperbolic complex symmetric gravitational theory can automatically free from the potential problem of negative energy ghost states. Furthermore,the double complex symmetric gravitational action in the double noncommutative spacetime can be constructed by extending the double complex coordinates to the double noncommutative relation satisfied and doubling the Moyal star product.
