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…

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…

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

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.

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…
