Abstract
In this paper we study the extent to which Golodness may be transferred along morphisms of DG-algebras. In particular, we show that if is a so-called fiber invariant ideal, then Golodness of is equivalent to Golodness of the initial ideal of . We use this to transfer Golodness results for monomial ideals to more general classes of ideals. We also prove that any so-called rainbow monomial ideal with linear resolution defines a Golod ring; this result encompasses and generalizes many known Golodness results for classes of monomial ideals. We then combine the techniques developed to give a concise proof that maximal minors of (sparse) generic matrices define Golod rings, independent of characteristic.
