  In the recent paper "The Nakayama functor and its completion for Gorenstein
algebras", a class of Gorenstein algebras over commutative noetherian rings was
introduced, and duality theorems for various categories of representations were
established. The manuscript on hand provides more context to the results
presented in the aforementioned work, identifies new classes of Gorenstein
algebras, and explores their behaviour under standard operations like taking
tensor products and tilting.
