"Duality and GT actions on Tangles" (Marcy Robertson, Melbourne)

12.08.2024 15:00 – 16:00

I will describe how one uses cyclic structure on the operad of parenthesized braids to determine an action of the Grothendieck-Teichm\”uller group, $GT$, on a category of “parenthesized tangles”. This action extends to a $GT$-action on a categorical models for virtual and welded tangles which, at least conjecturally, should extend to an action of the Kashiwara-Vergne symmetry groups. This talk contains joint work with Chandan Singh
