DESCRIPTION:Speakers: Hank Chen (BIMSA)\n\nThis talk is based on my recent
  joint works arXiv:2405.18625\, arXiv:2307.03831 with Joaquin Liniado and 
 Florian Girelli.\nBased on Lie 2-groups\, I will introduce a 3d topologica
 l-holomorphic integrable field theory W\, which can be understood as a hig
 her-dimensional version of the Wess-Zumino-Witten model. By studying its h
 igher currents and holonomies\, it is revealed that W is related to both t
 he raviolo VOAs of Garner- Williams --- a type of derived higher quantum a
 lgebra --- and the lasagna modules of Manolescu-Walker-Wedrich --- a type 
 of 4d higher-skein invariant. I will then analyze the Noether charges of W
 \, and prove that its symmetries are encoded by a derived version of the K
 ac-Moody algebra. If time allows\, I will discuss how W enjoys a certain n
 otion of "higher Lax integrability".\n\nhttps://events.perimeterinstitute.
