 chords using microlocal sheaf theory\n	\n	Abstract: We show that\, for close
 d Legendrians in 1-jet bundles\, when there is a sheaf with singular suppo
 rt on the Legendrian\, then (1) its self Reeb chords are bounded from belo
 w by half the sum of Betti numbers\, and (2) the Reeb chords between itsel
 f and its Hamiltonian push off is bounded from below by Betti numbers when
  the -norm of the Hamiltonian is small. I will show how to visualize Reeb 
 chords/Lagrangian intersections in sheaf theory\, and then explain the dua
 lity exact triangle and the persistence structure used in the proof. If ti
 me permits\, I will state a conjecture on the relative Calabi-Yau structur
 e that arises from the duality exact triangle.(2/3) Title: TBAAbstract: TB
