摘要
From Hodge ideals of singularities, we obtain the Hodge moduli algebras which are Gorenstein local algebras in some cases. We recover the $J$-functions of simple elliptic singularities from these local algebras. This extends the earlier work of M. G. Eastwood that he constructed the $J$-functions from the Tjurina algebras of simple elliptic singularities.
