# Quantization of conic Lagrangian submanifolds of cotangent bundles

@article{Guillermou2012QuantizationOC, title={Quantization of conic Lagrangian submanifolds of cotangent bundles}, author={St'ephane Guillermou}, journal={arXiv: Symplectic Geometry}, year={2012} }

Let $M$ be a manifold and $\Lambda$ a compact exact connected Lagrangian submanifold of $T^*M$. We can associate with $\Lambda$ a conic Lagrangian submanifold $\Lambda'$ of $T^*(M\times R)$. We prove that there exists a canonical sheaf $F$ on $M\times R$ whose microsupport is $\Lambda'$ outside the zero section. We deduce the already known results that the Maslov class of $\Lambda$ is $0$ and that the projection from $\Lambda$ to $M$ induces isomorphisms between the homotopy groups.
