Abstract

Let (S, m, k) and (T, n, k) be local rings, and let R denote their fiber product over their common residue field k. Inspired by work of Nasseh and Sather-Wagstaff, we explore consequences of the vanishing of Tor(m)(R) (M, N) for various values of m, where M and N are finitely generated R-modules. (AU)
