Abstract

Let XX be a compact real analytic manifold, and let TXT^*X be its cotangent bundle. Let Sh(X)Sh(X) be the triangulated dg category of bounded, constructible complexes of sheaves on XX. In this paper, we develop a Fukaya AA_\infty-category Fuk(TX)Fuk(T^*X) whose objects are exact, not necessarily compact Lagrangian branes in the cotangent bundle. We write TwFuk(TX)Tw Fuk(T^*X) for the AA_\infty-triangulated envelope of Fuk(TX)Fuk(T^*X) consisting of twisted complexes of Lagrangian branes. Our main result is that Sh(X)Sh(X) quasi-embeds into TwFuk(TX)Tw Fuk(T^*X) as an AA_\infty-category. Taking cohomology gives an embedding of the corresponding derived categories.
