%0 Journal Article %T A Dedekind-Mertens theorem for power series rings %A Neil Epstein %A Jay Shapiro %J Mathematics %D 2014 %I arXiv %X We prove a power series ring analogue of the Dedekind-Mertens lemma. Along the way, we give limiting counterexamples, we note an application to integrality, and we correct an error in the literature. %U http://arxiv.org/abs/1402.1100v2
