Abstract

In this article we prove that there exists a relation between dd-pre-Calabi-Yau morphisms introduced by M. Kontsevich, A. Takeda and Y. Vlassopoulos and cyclic AA_{\infty}-morphisms, extending a result proved by D. Fern\'andez and E. Herscovich. This leads to a functor between the category of dd-pre-Calabi-Yau structures and the partial category of AA_{\infty}-categories of the form AA[d1]\mathcal{A}\oplus\mathcal{A}^*[d-1] with A\mathcal{A} a graded quiver and whose morphisms are the data of an AA_{\infty}-structure on AB[d1]\mathcal{A}\oplus\mathcal{B}^*[d-1] together with AA_{\infty}-morphisms A[1]B[d]A[1]A[d]\mathcal{A}[1]\oplus\mathcal{B}^*[d]\rightarrow \mathcal{A}[1]\oplus\mathcal{A}^*[d] and A[1]B[d]B[1]B[d]\mathcal{A}[1]\oplus\mathcal{B}^*[d]\rightarrow \mathcal{B}[1]\oplus\mathcal{B}^*[d].
