DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/59/">
 Where are the complex curves in Khovanov homology?</a>\nby Kyle Hayden (Co
 lumbia Univ.) as part of CRM - Séminaire du CIRGET / Géométrie et Topol
 ogie\n\n\nAbstract\nSince the advent of gauge theory\, many modern tools e
 xhibit a close connection with complex curves and a heightened sensitivity
  to objects from the complex realm. Surprisingly\, this is true even for K
 hovanov homology\, whose construction is combinatorial rather than geometr
 ic. I will discuss this in the context of joint work with Isaac Sundberg t
 hat uses Khovanov homology to study knotted surfaces in 4-space\, especial
 ly (compact pieces of) complex curves in the 4-ball.\n
