A linear variant of GT
@inproceedings{Pop2021ALV, title={A linear variant of GT}, author={Florian Pop and Adam Topaz}, year={2021} }
In this work, we introduce a variant of the Grothendieck-Teichmüller group, defined in terms of complements of hyperplane arrangements and pro-l two-step nilpotent fundamental groups, and prove that it is isomorphic to the absolute Galois group of Q.

SummaryWe propose a new way to describe, universally, thel-adic Galois representations associated to each “almost pro-l” tower of etale coverings ofP1\{0, 1, ∞}. This generalizes our universal power…
