DESCRIPTION:[b]Speaker: Muze Ren [/b](​University of Strasbourg).\n\n[b]Ab
 stract:[/b] \n​Multiple zeta values (MZVs) are real numbers that generali
 ze Riemann zeta functions at integer values. MZVs have three distinguishe
 d set of relations\, namely the stuffle relation\, shuffle relation and r
 egularization relations\, those relations has deep connection with the th
 eory of motives. G. Racinet introduced the double shuffle Lie algebra (dm
 r_0)  and use it to study formally those three set of relations. Kashiwar
 a-Vergne Lie algebra (krv_2) was introduced by A. Alekseev and C. Torossi
 an when they give a proof of Kashiwar--Vergne conjecture in Lie theory.\n
 \nIn this talk\, I want to use the notion of Brunnian braids to give a to
 pological description of dmr_0 and symmetric krv_2.   And prove that dmr_
 0 injects to symmetric krv_2. This talk is based on the preprint arXiv:26
 05.20844 [math.QA] and arXiv:2607.28163 [math.QA].
