Koszul algebra is a concept from the field of algebra, particularly in the area of homological algebra and commutative algebra. It is named after Jean-Pierre Serre, who introduced the notion of Koszul complexes, and it has since been developed further in various contexts. A Koszul algebra is generally defined in connection with a certain type of graded algebra that is associated with a sequence of elements in a ring.
