Query: Generalizing the notion of Koszul algebra   We introduce a generalization of the notion of a Koszul algebra, which
includes graded algebras with relations in different degrees, and we establish
some of the basic properties of these algebras. This class is closed under
twists, twisted tensor products, regular central extensions and Ore extensions.
We explore the monomial algebras in this class and we include some well-known
examples of algebras that fall into this class.
