Abstract
We argue that recent results in string perturbation theory indicate that the four-graviton amplitude of four-dimensional N=8 supergravity might be ultraviolet finite up to eight loops. We similarly argue that the h-loop M-graviton amplitude might be finite for h<7+M/2.
摘要
我们认为，弦微扰理论的最新结果表明，四维N = 8超引力的四引力子振幅在八圈之前可能是紫外有限的。我们同样认为，对于h < 7 + M/2，h圈M引力子振幅可能是有限的。
