Is $D$ symmetric monoidal?

Algebraic Topology 2020-01-22 v1

Abstract

We verify that a certain functor D ⁣:SpΣ(Ch+)ChD\colon\text{Sp}^\Sigma(\text{Ch}^+)\to\text{Ch} is symmetric monoidal. This functor is used elsewhere in developing the model category theory of symmetric spectra and of chain complexes graded over N\mathbb{N} or Z\mathbb{Z}.
