Let R = R0 ⊕ R1 ⊕ R2 ⊕ ⋯ be a graded algebra over a field K such that R0 is a finite product of copies of K and each Ri is finite dimensional over K. Set J = R1 ⊕ R2 ⊕ ⋯ and S = ⊕n ≥ 0 ExtRn (R / J, R / J). We study the properties of the categories of graded R-modules and S-modules that relate to the noetherianity of R. We pay particular attention to the case when R is a Koszul algebra and S is the Koszul dual to R.
