摘要
Gravity amplitudes are, via the Kawai-Lewellen-Tye relations intimately linked to products of Yang-Mills amplitudes. Explicitly, this shows up in computations of N = 8 supergravity where the perturbative expansion and ultraviolet behavior of this theory is akin to N = 4 super-Yang-Mills at least through three loops. Full persistence to all loop orders would be truly remarkable and imply finiteness of N = 8 supergravity in four dimensions.
