The cosmic Galois group and extended Steinmann relations for planar N $$ \mathcal{N} $$ = 4 SYM amplitudes
Abstract We describe the minimal space of polylogarithmic functions that is required to express the six-particle amplitude in planar N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory through six and seven loops, in the NMHV and MHV sectors respectively. This space respects a set of extended Steinmann...
