DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/20/
 ">Tropical characteristic classes</a>\nby Alex Esterov (HSE Moscow) as par
 t of (LAGARTOS) Latin American Real and Tropical Geometry Seminar\n\n\nAbs
 tract\nTo every affine algebraic variety one can assign its tropical fan\,
  which remembers a lot about the intersection theory of the variety. Moreo
 ver\, to every k-dimensional variety one can associate its tropical charac
 teristic classes (a tuple of tropical fans of dimensions from 0 to k)\, wh
 ich remember much more. I will introduce tropical characteristic classes\,
  discuss how to compute them\, point out their relations to some other obj
 ects of similar nature (such as CSM classes of matroids and refined tropic
 alizations)\, and tell about some applications to enumerative geometry and
  singularity theory.\n
