The 5-Mass Kite Integral Family

Description

In this talk I will present upcoming work with M. Giroux, A. Pokraka and Y. Sohnle on an analytic solution of the kite integral family with 5 parameters. Through its two sunrise sub-topologies, this family is related to two elliptic curves. We show that finding an epsilon-form basis of this integral family is connected to finding a „good“ parametrization on the two respective tori and that this can be done systematically at least for the kite family. Having found the epsilon basis, one can then express all integrals of the kite family in terms of EMPLs on these tori.
