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…

Skein-valued mirror curves for toric CY3 strips

Mingyuan Hu, Vivek Shende

For a smooth semi-projective toric Calabi-Yau 3-fold containing no compact surface, we show the count of all-genus holomorphic curves with boundary on a single Aganagic-Vafa brane…

Microsheaf composition of Lagrangian correspondences

Wenyuan Li, David Nadler, Vivek Shende

In exact symplectic manifolds whose Liouville flow is gradientlike for a proper Morse function, one can associate conic microsheaves to eventually conic exact Lagrangians. Here we…

The microlocal Riemann-Hilbert correspondence for complex contact manifolds

Laurent Côté, Christopher Kuo, David Nadler +1

Kashiwara showed in 1996 that the categories of microlocalized D-modules can be canonically glued to give a sheaf of categories over a complex contact manifold. Much more recently,…

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…

On the Hochschild cohomology of Tamarkin categories

Christopher Kuo, Vivek Shende, Bingyu Zhang

To any open subset of a cotangent bundle, Tamarkin has associated a certain quotient of a category of sheaves. Here we show that the Hochschild cohomology of this category agrees w…
