Newton-Okounkov polyhedra for character varieties and configuration spaces

Christopher Manon

Published 2014-03-17, updated 2016-07-13Version 2

We construct families of Newton-Okounkov bodies for the free group character varieties and configuration spaces of any connected reductive group. We use this construction to give a proof that these spaces are Cohen-Macaulay.
