The pentagon equation and the confluence relations

Quantum Algebra 2022-02-21 v2 Number Theory

Abstract

We show an equivalence of Drinfeld's pentagon equation and Hirose-Sato's confluence relations. As a corollary, we obtain a pentagon-free presentation of the Grothendieck-Teichm\"{u}ller group GRT1GRT_1 and associators.
