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…

On the compatibility of the Betti harmonic coproduct with cyclotomic filtrations

Benjamin Enriquez, Khalef Yaddaden

In a previous paper, the second author introduced a Betti counterpart of -cyclotomic double shuffle theory for any . The construction is based on the group algebra of…

A categorical formulation of the Deligne-Terasoma approach to double shuffle theory

Benjamin Enriquez, Khalef Yaddaden

In this paper, we introduce the notion of a bimodule with a factorization structure (BFS) and show that such a structure gives rise to an algebra morphism. We then prove that this…

An alternative -form of the cyclotomic double shuffle Lie algebra

Hidekazu Furusho, Khalef Yaddaden

We present an alternative -form for Racinet's cyclotomic double shuffle Lie algebra, inspired by the double shuffle relations among congruent multiple zeta values studi…

On a conjecture of Zhao related to standard relations among cyclotomic multiple zeta values

Henrik Bachmann, Khalef Yaddaden

We provide a proof of a conjecture by Zhao concerning the structure of certain relations among cyclotomic multiple zeta values in weight two. We formulate this conjecture in a broa…
