Abstract

Monoidal categories enriched in a braided monoidal category V\mathcal{V} are classified by braided oplax monoidal functors from V\mathcal{V} to the Drinfeld centers of ordinary monoidal categories. In this article, we prove that this classifying functor is strongly monoidal if and only if the original V\mathcal{V}-monoidal category is tensored over V\mathcal{V}. We then define a completion operation which produces a tensored V\mathcal{V}-monoidal category C\overline{\mathcal{C}} from an arbitrary V\mathcal{V}-monoidal category C\mathcal{C}, and we determine many equivalent conditions which imply C\mathcal{C} and C\overline{\mathcal{C}} are V\mathcal{V}-monoidally equivalent. Since being tensored is a property of the underlying V\mathcal{V}-category of a V\mathcal{V}-monoidal category, we begin by studying the equivalence between (tensored) V\mathcal{V}-categories and oplax (strong) V\mathcal{V}-module categories respectively. We then define the completion operation for V\mathcal{V}-categories, and adapt these results to the V\mathcal{V}-monoidal setting.
