The homological determinant conjecture for noetherian connected graded AS Gorenstein algebras

Let $A$ be a noetherian connected graded Artin-Schelter Gorenstein algebra, and let $\mu_A$ denote its Nakayama automorphism. Let $\operatorname{hdet}$ denote the homological determinant. The homological determinant conjecture. One has

$$\operatorname{hdet}(\mu_A)=1.$$

This conjecture was made in the cited earlier work, and the theorem immediately preceding it proves the assertion when $A$ satisfies the epsilon-condition; the supplied text does not establish the conjecture for every algebra in its stated class.
