A Stabilizer Interpretation of Double Shuffle Lie Algebras
According to Racinet’s work, the scheme of double shuffle and regularization relations between cyclotomic analogs of multiple zeta values has the structure of a torsor over a pro-unipotent |$\mathbb Q$|-algebraic group |$\sf{DMR}_0$|, which is an algebraic subgroup of a pro-unipotent |$\mathbb Q$|-algebraic group of outer automorphisms of a free Lie …
