摘要

最近,Bonisch-Fischbach-Klemm-Nega-Safari通过数值计算发现,l-环Banana Feynman振幅在大复杂结构极限处的领先渐近性可以用(1,…,1)次Fano超曲面F in (P^1)^{1 +1}的Gamma类来描述。我们用F的伽玛猜想型结果证实了这一观察。

Asymptotics of the Banana Feynman amplitudes at the large complex structure limit
Recently Bonisch-Fischbach-Klemm-Nega-Safari discovered, via numerical computation, that the leading asymptotics of the l-loop Banana Feynman amplitude at the large complex structure limit can be described by the Gamma class of a degree (1,...,1) Fano hypersurface F in (P^1)^{l+1}. We confirm this observation by using a Gamma-conjecture type result for F.
