DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OISTRTS/24/"
 >Real Springer fibers and odd arc algebras</a>\nby Arik Wilbert (Universit
 y of South Alabama) as part of OIST representation theory seminar\n\n\nAbs
 tract\nArc algebras were introduced by Khovanov in a successful attempt to
  lift the quantum sl2 Reshetikhin-Turaev invariant for tangles to a homolo
 gical invariant. When restricted to knots and links\, Khovanov’s homolog
 y theory categorifies the Jones polynomial. Ozsváth-Rasmussen-Szabó disc
 overed a different categorification of the Jones polynomial called odd Kho
 vanov homology. Recently\, Naisse-Putyra were able to extend odd Khovanov 
 homology to tangles using so-called odd arc algebras which were originally
  constructed by Naisse-Vaz. The goal of this talk is to discuss a geometri
 c approach to understanding odd arc algebras and odd Khovanov homology usi
 ng Springer fibers over the real numbers. This is joint work with J. N. Eb
 erhardt and G. Naisse.\n
