We study the syzygies of Koszul algebras. The main result asserts that a Koszul algebra has syzygies whose degrees growth as the degrees of the syzygies of a complete intersection of quadrics. More precisely, if R is a Koszul algebra and t_i is the largest degree of a i-th syzygy of R, we show that t_i is at most 2i.

Abstract
We study the syzygies of Koszul algebras. The main result asserts that a Koszul algebra has syzygies whose degrees growth as the degrees of the syzygies of a complete intersection of quadrics. More precisely, if R is a Koszul algebra and t_i is the largest degree of a i-th syzygy of R, we show that t_i is at most 2i.File in questo prodotto:
