DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MAAGC2024/3/
 ">Mather classes via small resolutions</a>\nby Minyoung Jeon (University o
 f Georgia) as part of MAAGC 2024\n\n\nAbstract\nThe Chern-Mather class is 
 a characteristic class\, generalizing the Chern class of a tangent bundle 
 of a nonsingular variety to a singular variety. It uses the Nash-blowup fo
 r a singular variety instead of the tangent bundle. In this talk\, we cons
 ider Schubert varieties\, known as singular varieties in most cases\, in t
 he even orthogonal Grassmannians and discuss the work computing the Chern-
 Mather class of the Schubert varieties by the use of the small resolution 
 of Sankaran and Vanchinathan with Jones’ technique. We also describe the
  Kazhdan-Lusztig class of Schubert varieties in Lagrangian Grassmannians\,
  as an analogous result. If time permitted\, we discuss the application of
  Jones’s method on K-orbit closures in flag varieties\, as a joint work 
 with Graham and Scott.\n
