DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/177/">A 
 tropical approach to the enriched count of bitangents to quartic curves</a
 >\nby Kris Shaw (University of Oslo) as part of ZAG (Zoom Algebraic Geomet
 ry) seminar\n\n\nAbstract\nUsing A1 enumerative geometry Larson and Vogt h
 ave provided an enriched count of the 28 bitangents to a quartic curve. In
  this talk\, I will explain how these enriched counts can be computed comb
 inatorially using tropical geometry. I will also introduce an arithmetic a
 nalogue of Viro’s patchworking for real algebraic curves which\, in some
  cases\, retains enough data to recover the enriched counts. This talk is 
 based on joint work with Hannah Markwig and Sam Payne.\n
