Calabi–Yau structure on the Chekanov–Eliashberg algebra of a Legendrian sphere

Year: 2025
Type: article
Abstract: We prove that the Chekanov-Eliashberg algebra of a horizontally displaceable n-dimensional Legendrian sphere in the contactization of a Liouville manifold is an .nC1/-Calabi-Yaudifferential graded algebra.In particular it means that there is a quasi-isomorphism of DG bimodules between the diagonal bimodule and the inverse dualizing bimodule associated to the Chekanov-Eliashberg algebra.On some cyclic version of these bimodules, computing the Hochschild homology and cohomology of the Chekanov-Eliashberg algebra, we construct A 1 -operations and show that the Calabi-Yau isomorphism extends to a family of maps satisfying the A 1 -functor equations.53D42, 57R58 1.
