DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/56/
 ">Higher spin representations of the Yangian of sl_2 and R-matrices</a>\nb
 y Yaping Yang (University of Melbourne) as part of Algebra and Geometry Se
 minar @ HKUST\n\nLecture held in 4472.\nAbstract: TBA\n\nFor the Yangian o
 f sl_2\, higher spin representations are tensor products of the evaluation
  pullback of the $\\ell_i+1$-dimensional irreducible representations of sl
 _2\, where $\\ell_i$ are the highest weights. In my talk\, I will give a g
 eometric realization of the higher spin representations in terms of the cr
 itical cohomology of representations of the quiver with potential of Bykov
  and Zinn-Justin.  I will also talk about the construction of R-matrices v
 ia the lattice model and the weight functions.\n\nThis is based on my join
 t work with Paul Zinn-Justin.\n
