Relations between elliptic modular graphs
Abstract We consider certain elliptic modular graph functions that arise in the asymptotic expansion around the non-separating node of genus two string invariants that appear in the integrand of the D 8ℛ4 interaction in the low momentum expansion of the four graviton amplitude in type II superstring...
