Calabi-yau properties of down-up dg algebras

WebWhen the rank r(M) of M belongs to {1,2,3}, we compute H(A) case by case. The computational results in this paper give substantial support for the research of the various homological properties of such DG algebras.

WebWe also give a criterion to judge whether two DG free algebras are isomorphic. As an application, we consider the case of n = 2. Based on the isomorphism classification, we compute the cohomology graded algebras of non-trivial DG free algebras with two generators, and show that all those non-trivial DG free algebras are Koszul and Calabi …
