We study the truncated microsupport SS k of sheaves on a real manifold. Applying our results to the case of F = RHom D (M , O), the complex of holomorphic solutions of a coherent D-module M , we show that SS k (F) is completely determined by the characteristic variety of M. As an application, we obtain an extension theorem for the sections of H j (F), j <(More)
The cotangent bundle T * X to a complex manifold X is classically endowed with the sheaf of k-algebras W T * X of deformation quantization, where k := W {pt} is a subfield of C[[, −1 ]. Here, we construct a new sheaf of k-algebras W t T * X which contains W T * X as a subalgebra and an extra central parameter t. We give the symbol calculus for this algebra(More)
Let X be a complex manifold, V a smooth involutive submani-fold of T * X, M a microdifferential system regular along V , and F an R-constructible sheaf on X. We study the complex of temperate microfunction solutions of M associated with F , that is, the complex RHom DX (M, T µhom(F, O X)). We give a bound to its micro-support and solve the Cauchy problem(More)
We study modules over the algebroid stack W X of deformation quantization on a complex symplectic manifold X and recall some results: construction of an algebra for ⋆-products, existence of (twisted) simple modules along smooth Lagrangian submanifolds, perversity of the complex of solutions for regular holonomic W X-modules, finiteness and duality for the(More)
