On the Drinfeld generators of grt_1(k) and Gamma-functions for associators

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/74079We prove that the Drinfeld generators of grt_1(k) span the image of this Lie algebra in the abelianization of the commutator of the free Lie algebra with two generators. We show that this result implies Gamma-function formulas for arbitrary associators.Quantum AlgebraOn the Drinfeld generators of grt_1(k) and Gamma-functions for associatorstext
