On the irregular Riemann-Hilbert correspondence

Andrea D'Agnolo, Masaki Kashiwara

The original Riemann-Hilbert problem asks to find a Fuchsian ordinary differential equation with prescribed singularities and monodromy in the complex line. In the early 1980's Kas…

On a topological counterpart of regularization for holonomic D-modules

Andrea D'Agnolo, Masaki Kashiwara

On a complex manifold, the embedding of the category of regular holonomic D-modules into that of holonomic D-modules has a left quasi-inverse functor $\mathcal{M}\mapsto\mathcal{M}…

Enhanced nearby and vanishing cycles in dimension one and Fourier transform

Andrea D'Agnolo, Masaki Kashiwara

Enhanced ind-sheaves provide a suitable framework for the irregular Riemann-Hilbert correspondence. In this paper, we give some precisions on nearby and vanishing cycles for enhanc…

Enhanced specialization and microlocalization

Andrea D'Agnolo, Masaki Kashiwara

Enhanced ind-sheaves provide a suitable framework for the irregular Riemann-Hilbert correspondence. In this paper, we show how Sato's specialization and microlocalization functors…

Topological computation of some Stokes phenomena on the affine line

Andrea D'Agnolo, Marco Hien, Giovanni Morando +1

Let be a holonomic algebraic -module on the affine line, regular everywhere including at infinity. Malgrange gave a complete description of the Fourier-Lap…

Enhanced perversities

Andrea D'Agnolo, Masaki Kashiwara

The Riemann-Hilbert correspondence embeds the triangulated category of (not necessarily regular) holonomic D-modules into that of -constructible enhanced ind-sheaves. Th…

Riemann-Hilbert correspondence for holonomic D-modules

Andrea D'Agnolo, Masaki Kashiwara

The classical Riemann-Hilbert correspondence establishes an equivalence between the triangulated category of regular holonomic D-modules and that of constructible sheaves. In this…

On a reconstruction theorem for holonomic systems

Andrea D'Agnolo, Masaki Kashiwara

Let X be a complex manifold. The classical Riemann-Hilbert correspondence associates to a regular holonomic system M the C-constructible complex of its holomorphic solutions. Denot…

On the Laplace transform for tempered holomorphic functions

Andrea D'Agnolo

In order to discuss the Fourier-Sato transform of not necessarily conic sheaves, we compensate the lack of homogeneity by adding an extra variable. We can then obtain Paley-Wiener…

Morita classes of microdifferential algebroids

Andrea D'Agnolo, Pietro Polesello

Projective cotangent bundles of complex manifolds are the local models of complex contact manifolds. Such bundles are quantized by the algebra of microdifferential operators (a loc…

On quantization of complex symplectic manifolds

Andrea D'Agnolo, Masaki Kashiwara

Let X be a complex symplectic manifold. By showing that any Lagrangian subvariety has a unique lift to a contactification, we associate to X a triangulated category of regular holo…

A note on quantization of complex symplectic manifolds

Andrea D'Agnolo, Masaki Kashiwara

To a complex symplectic manifold X we associate a canonical quantization algebroid. Our construction is similar to that of Polesello-Schapira's deformation-quantization algebroid,…

Regular holonomic D[[h]]-modules

Andrea D'Agnolo, Stephane Guillermou, Pierre Schapira

We describe the category of regular holonomic modules over the ring D[[h]] of linear differential operators with a formal parameter h. In particular, we establish the Riemann-Hilbe…

Quantization of complex Lagrangian submanifolds

Andrea D'Agnolo, Pierre Schapira

Let be a smooth Lagrangian submanifold of a complex symplectic manifold . We construct twisted simple holonomic modules along in the stack of deformation-quantization mo…

Sheaves and D-modules in integral geometry

Andrea D'Agnolo

Integral geometry deals with those integral transforms which associate to ``functions'' on a manifold their integrals along submanifolds parameterized by another manifold. Basic pr…

Deformation-Quantization of Complex Involutive Submanifolds

Andrea D'Agnolo, Pietro Polesello

The sheaf of rings of WKB operators provides a deformation-quantization of the cotangent bundle to a complex manifold. On a complex symplectic manifold there may not exist a sh…

On twisted microdifferential modules I. Non-existence of twisted wave equations

Andrea D'Agnolo, Pierre Schapira

Using the notion of subprincipal symbol, we give a necessary condition for the existence of twisted D-modules simple along a smooth involutive submanifold of the cotangent bundle t…

Stacks of twisted modules and integral transforms

Andrea D'Agnolo, Pietro Polesello

Stacks were introduced by Grothendieck and Giraud and are, roughly speaking, sheaves of categories. Kashiwara developed the theory of twisted modules, which are objects of stacks l…

On Dwork cohomology and algebraic D-modules

Francesco Baldassarri, Andrea D'Agnolo

After works by Katz, Monsky, and Adolphson-Sperber, a comparison theorem between relative de Rham cohomology and Dwork cohomology is established in a paper by Dimca-Maaref-Sabbah-S…
