DESCRIPTION:Title: <a href="https://researchseminars.org/talk/2021PRCSG/2/
 ">Augmentations and ruling polynomials for Legendrian graphs</a>\nby Byung
 hee AN (Kyungpook National University) as part of 2021 Pacific Rim Complex
  & Symplectic Geometry Conference\n\n\nAbstract\nIn this talk\, we will sh
 ow the equivalence between two Legendrian isotopy invariants of Legendrian
  graphs: (i) augmentation number via point-counting over a finite field fo
 r the augmentation variety of the associated Chekanov-Eliashberg DGA\, and
  (ii) the ruling polynomial via combinatorics of the decompositions of the
  associated front projections. This is a joint work with Youngjin Bae(Inch
 eon National University) and Tao Su(Yau Mathematical Sciences Center\, Tsi
 nghua University).\n
