An extended FNUG Seminar with guest researchers

Speaker: Clement Delcamp (​IHES).Abstract: TBA

Speaker: Muze Ren (​University of Strasbourg).Abstract: ​Multiple zeta values (MZVs) are real numbers that generalize Riemann zeta functions at integer values. MZVs have three distinguished set of relations, namely the stuffle relation, shuffle relation and regularization relations, those relations has deep connection with the theory of motives. G. Racinet introduced the double shuffle Lie algebra (dmr_0)  and use it to study formally those three set of relations. Kashiwara-Vergne Lie algebra (krv_2) was introduced by A. Alekseev and C. Torossian when they give a proof of Kashiwar--Vergne conjecture in Lie theory.In this talk, I want to use the notion of Brunnian braids to give a topological 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:2605.20844 [math.QA] and arXiv:2607.28163 [math.QA].

FNUG and NAFA invite to a NiSE Webinar

The purpose with this event is to inspire your teaching in the laboratory. With a setoff in concrete experiences, we will explore ways to conduct lab work with different levels of student driven engagement in the lab work. Themes that will be address

At this research seminar, researchers and students from FNUG present updates from their current research. Beforehand, there will be a potluck lunch.

Poster Session and presentation
