Lagrangian cobordism functor in microlocal sheaf theory I

W Li - Journal of Topology, 2023 - Wiley Online Library
Abstract Let Λ±Λ_± be Legendrian submanifolds in the cosphere bundle T∗,∞ MT^*,∞M.
Given a Lagrangian cobordism LL of Legendrians from Λ− Λ_- to Λ+ Λ_+, we construct a …

C Kuo, W Li - arXiv preprint arXiv:2408.04085, 2024 - arxiv.org
For an oriented manifold $ M $ and a compact subanalytic Legendrian $\Lambda\subseteq
S^* M $, we construct a canonical strong smooth relative Calabi--Yau structure on the …

Simplicial descent for Chekanov–Eliashberg dg‐algebras

J Asplund - Journal of Topology, 2023 - Wiley Online Library
We introduce a type of surgery decomposition of Weinstein manifolds that we call simplicial
decompositions. The main result of this paper is that the Chekanov–Eliashberg dg‐algebra …

On Fukaya categories and prequantization bundles

T Kuwagaki, A Petr, V Shende - arXiv preprint arXiv:2406.08852, 2024 - arxiv.org
We show: the Floer homology of (nonexact!) integral Lagrangians in an (nonexact!) integral
symplectic manifold can be computed in terms of exact Lagrangians in an exact filling of the …

Tangle contact homology

J Asplund - International Journal of Mathematics, 2024 - World Scientific
Knot contact homology is an ambient isotopy invariant of knots and links in ℝ 3. The purpose
of this paper is to extend this definition to an ambient isotopy invariant of tangles and prove …

Singular Legendrian unknot links and relative Ginzburg algebras

J Asplund - arXiv preprint arXiv:2311.03330, 2023 - arxiv.org
We associate to a quiver and a subquiver $(Q, F) $ a stopped Weinstein manifold $ X $
whose Legendrian attaching link is a singular Legendrian unknot link $\varLambda $. We …

Invariants of the Legendrian lift of an exact Lagrangian submanifold in the circular contactization of a Liouville manifold

A Petr - 2022 - hal.science
We study the relations between an exact Lagrangian submanifold L in a Liouville manifold P
and one of its Legendrian lift in the circular contactization S1× P. Unlike the well-studied …
