Abstract

For an oriented manifold MM and a compact subanalytic Legendrian ΛSM\Lambda \subseteq S^*M, we construct a canonical strong smooth relative Calabi--Yau structure on the microlocalization at infinity and its left adjoint mΛl:μshΛ(Λ)ShΛ(M)0:mΛm_\Lambda^l: \operatorname{\mu sh}_\Lambda(\Lambda) \rightleftharpoons \operatorname{Sh}_\Lambda(M)_0 : m_\Lambda between compactly supported sheaves on MM with singular support on Λ\Lambda and microsheaves on Λ\Lambda. We also construct a canonical strong Calabi-Yau structure on microsheaves μshΛ(Λ)\operatorname{\mu sh}_\Lambda(\Lambda). Our approach does not require local properness and hence does not depend on arborealization. We thus obtain a canonical smooth relative Calabi-Yau structure on the Orlov functor for wrapped Fukaya categories of cotangent bundles with Weinstein stops, such that the wrap-once functor is the inverse dualizing bimodule.
