A remark on monoidal structure and homological mirror symmetry

Tatsuki Kuwagaki

For a symplectic geometry , suppose the (derived) Fukaya category of is equipped with a monoidal structure. Then its Balmer spectrum recovers a mirror …

Almost mathematics, Persistence module, and Tamarkin category

Tatsuki Kuwagaki, Bingyu Zhang

We give a precise unification of three theories that are widely used by symplectic geometers: (Almost) modules over the Novikov ring, Persistence modules, and the Tamarkin category…

Hodge microsheaves on cotangent bundles and plumbings

Tatsuki Kuwagaki, Takahiro Saito

We introduce and study the category of Hodge microsheaves which is a Hodge-version of the category of microsheaves for a certain class of holomorphic exact symplectic manifolds. We…

On the generic existence of WKB spectral networks/Stokes graphs

Tatsuki Kuwagaki

We prove the generic existence of spectral networks for a large class of spectral data.

On Fukaya categories and prequantization bundles

Tatsuki Kuwagaki, Adrian Petr, Vivek Shende

We show: the Floer homology over the Novikov ring of (nonexact!) rational Lagrangians in an (nonexact!) integral symplectic manifold can be computed in terms of exact Lagrangians i…

Tamarkin's separation theorem for non-compact objects in cotangent bundles

Yuichi Ike, Tatsuki Kuwagaki

In this short note, we prove a Tamarkin-type separation theorem for possibly non-compact subsets in cotangent bundles.

Almost equivalences between Tamarkin category and Novikov sheaves

Tatsuki Kuwagaki

We revisit the relationship between the Tamarkin's extra variable and Novikov rings. We prove that the equivariant version of Tamarkin category is almost equivalent (in the sen…

Adjoints, wrapping, and morphisms at infinity

Tatsuki Kuwagaki, Vivek Shende

For a localization of a smooth proper category along a subcategory preserved by the Serre functor, we show that morphisms in Efimov's algebraizable categorical formal punctured nei…

Microlocal categories over Novikov rings

Yuichi Ike, Tatsuki Kuwagaki

In this paper, we define a family of categories for each Weinstein manifold, which is an enhanced version of the category first introduced by Tamarkin. Using our categories, for an…

An introduction to sheaf quantization

Tatsuki Kuwagaki

The notion of sheaf quantization has many faces: an enhancement of the notion of constructible sheaves, the Betti counterpart of Fukaya--Floer theory, a topological realization of…

-Riemann-Hilbert correspondence

Tatsuki Kuwagaki

We formulate and prove a Riemann-Hilbert correspondence between -differential equations and sheaf quantizations, which can be considered as a correspondence between two kind…

Sheaf quantization from exact WKB analysis

Tatsuki Kuwagaki

A sheaf quantization is a sheaf associated to a Lagrangian brane. By using the results of exact WKB analysis, we sheaf-quantize spectral curves over the Novikov ring under some ass…

Mirror symmetry for perverse schobers from birational geometry

W. Donovan, T. Kuwagaki

Perverse schobers are categorical analogs of perverse sheaves. Examples arise from varieties admitting flops, determined by diagrams of derived categories of coherent sheaves assoc…

Categorification of Legendrian knots

Tatsuki Kuwagaki

Perverse schober defined by Kapranov--Schechtman is a categorification of the notion of perverse sheaf. In their definition, a key ingredient is certain purity property of perverse…

Irregular perverse sheaves

Tatsuki Kuwagaki

We introduce irregular constructible sheaves, which are -constructible with coefficients in a finite version of Novikov ring and special gradings. We show that the…

The nonequivariant coherent-constructible correspondence for toric stacks

Tatsuki Kuwagaki

The nonequivariant coherent-costructible correspondence is a microlocal-geometric interpretation of homological mirror symmetry for toric varieties conjectured by Fang-Liu-Treumann…

Categorical localization for the coherent-constructible correspondence

Yuichi Ike, Tatsuki Kuwagaki

We prove a microlocal counterpart of categorical localization for Fukaya categories in the setting of the coherent-constructible correspondence.

The nonequivariant coherent-constructible correspondence for toric surfaces

Tatsuki Kuwagaki

We prove the nonequivariant coherent-constructible correspondence conjectured by Fang-Liu-Treumann-Zaslow in the case of toric surfaces. Our proof is based on describing a semi-ort…
