A stabilizer interpretation of the (extended) linearized double shuffle Lie algebra
Annika Burmester, Khalef Yaddaden
The linearized double shuffle Lie algebra introduced by Brown reflects the depth-graded structure of multiple zeta values. In a previous paper, the first author introduced an exten…

An extension of the linearized double shuffle Lie algebra
Annika Burmester
The linearized double shuffle Lie algebra is a well-studied Lie algebra, which reflects the depth-graded structure of multiple zeta values. We introduce a generaliz…

On post-Lie structures for free Lie algebras
Annika Burmester, Ulf Kühn
We study post-Lie structures on free Lie algebras, the Grossman-Larson product on their enveloping algebras, and provide an abstract formula for its dual coproduct. This might be o…
