Abstract

It is known that every 3-dimensional noetherian Calabi-Yau algebra generated in degree 1 is isomorphic to a Jacobian algebra of a superpotential. Recently, S. P. Smith and the first author classified all superpotentials whose Jacobian algebras are 3-dimensional noetherian quadratic Calabi-Yau algebras. The main result of this paper is to classify all superpotentials whose Jacobian algebras are 3-dimensional noetherian cubic Calabi-Yau algebras. As an application, we show that if SS is a 3-dimensional noetherian cubic Calabi-Yau algebra and σ\sigma is a graded algebra automorphism of SS, then the homological determinant of σ\sigma can be calculated by the formula hdetσ=(detσ)2\operatorname{hdet} \sigma=(\operatorname{det} \sigma)^2 with one exception.
