Koszul代数R是一个N-分次K-代数,其剩余域K具有作为R-模的线性自由分解。我们给出了Koszul代数和Koszulness的强形式的各种刻画。讨论了Koszul代数合度的界的最新结果。最后,我们详细地讨论了Veronese代数和与超空间集合相关的代数的Koszul性质。
A Koszul algebra R is a N-graded K-algebra whose residue field K has a linear free resolution as an R-module. We present various characterizations of Koszul algebras and strong versions of Koszulness. Recent results on bounds of the degrees of the syzygies of a Koszul algebra are discussed. Finally we discuss in details the Koszul property of Veronese algebras and of algebras associated with collections of hyperspaces.
