平直宇宙背景下的引力单圈发散抵消项

One-loop counter Lagrangian of gravity on the flat universe background

在背景场方案下,用协变量子化方法求出了含耦合标量场的量子引力的单圈发散抵消项.结果表明,该抵消项为时间的幂次形式.

Using the background field method,find the one-loop divergence counter term of quantum gravity coupling scalar field in the framework of covariant quantization.The results show that the aforementioned counter term is a power law in time coordinates.
