Singular Legendrian unknot links and relative Ginzburg algebras

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 .We prove that the relative Ginzburg algebra of .Q; F / is quasi-isomorphic to the Chekanov-Eliashberg dg-algebra of .It follows that the Chekanov-Eliashberg dg-algebra of relative to its boundary dg-subalgebra, and the Orlov functor associated to the partially wrapped Fukaya category of X both admit a strong relative smooth Calabi-Yau structure.53D35, 53D42; 16E45 1.
