Projected distances for multi-parameter persistence modules

Nicolas Berkouk, Francois Petit

Relying on sheaf theory, we introduce the notions of projected barcodes and projected distances for multi-parameter persistence modules. Projected barcodes are defined as derived p…

A property of the interleaving distance for sheaves

Francois Petit, Pierre Schapira, Lukas Waas

Let be a real analytic manifold endowed with a distance satisfying suitable properties and let be a field. In [PS20], the authors construct a pseudo-distance on th…

Thickening of the diagonal and interleaving distance

Francois Petit, Pierre Schapira

Given a topological space , a thickening kernel is a monoidal presheaf on with values in the monoidal category of derived kernels on . A bi-thickenin…

Integral representation theorems for DQ-modules

David Gepner, Francois Petit

We identify the type of -linear structure inherent in the -categories which arise in the theory of Deformation Quantization modules. Using this structu…

Ephemeral persistence modules and distance comparison

Nicolas Berkouk, Francois Petit

We provide a definition of ephemeral multi-persistent modules and prove that the quotient of persistent modules by the ephemeral ones is equivalent to the category of -sheaves.…

Holomorphic Frobenius actions for DQ-modules

Francois Petit

Given a complex manifold endowed with a -action and a DQ-algebra equipped with a compatible holomorphic Frobenius action (F-action), we prove that if the $\mathb…

Tempered subanalytic topology on algebraic varieties

Francois Petit

On a smooth algebraic variety over , we build the tempered subanalytic and Stein tempered subanalytic sites. We construct the sheaf of holomorphic functions tempered at…

Quantization of spectral curves and DQ-modules

Francois Petit

Given an holomorphic Higgs bundle on a compact Riemann surface of genus greater than one, we construct a DQ-module supported by the spectral curve associated to this bundle. Then,…

The Codimension-Three conjecture for holonomic DQ-modules

Francois Petit

We prove an analogue for holonomic DQ-modules of the codimension-three conjecture for microdifferential modules recently proved by Kashiwara and Vilonen. Our result states that any…

Fourier-Mukai transform in the quantized setting

Francois Petit

We prove that a coherent DQ-kernel induces an equivalence between the derived categories of DQ-modules with coherent cohomology if and only if the graded commutative kernel associa…

The Lefschetz-Lunts formula for deformation quantization modules

Francois Petit

We adapt to the case of deformation quantization modules a formula of V. Lunts who calculates the trace of a kernel acting on Hochschild homology.

DG Affinity of DQ-modules

Francois Petit

In this paper, we prove the dg affinity of formal deformation algebroid stacks over complex smooth algebraic varieties. For that purpose, we introduce the triangulated category of…

A Riemann-Roch Theorem for dg Algebras

Francois Petit

Given a smooth proper dg-algebra , a perfect dg -module , and an endomorphism of , we define the Hochschild class of the pair with values in the Hochschild…
