Sheaf Quantization of Legendrian Isotopy

Symplectic Geometry 2018-10-31 v2

Abstract

Let {Λt}\{\Lambda^\infty_t\} be an isotopy of Legendrians (possibly singular) in a unit cosphere bundle SMS^*M. Let Sh(M,Λt)Sh(M, \Lambda^\infty_t) be the differential graded (dg) derived category of constructible sheaves on MM with singular support at infinity contained in Λt\Lambda^\infty_t. We prove that if the isotopy of Legendrians embeds into an isotopy of Weinstein hypersurfaces, then the categories Sh(M,Λt)Sh(M, \Lambda^\infty_t) are invariant.
