Title: Two notions of Krull dimension for differential graded algebras

Abstract: We will compare two different notions of a system of parameters for a homologically finite complex over a commutative noetherian local ring.  In particular, we will demonstrate that, while these notions differ in general, they agree when the complex admits a DG algebra structure.  We will also show that the corresponding notions of Krull dimension agree in the DG case. This is joint work with Sean Sather-Wagstaff.
