Lax monoidality for products of enriched higher categories (2305.15204v1)

Abstract: We prove that a lax $\mathbb{E}_{n+1}$-monoidal functor from $\mathcal V$ to $\mathcal W$ induces a lax $\mathbb{E}_n$-monoidal functor from $\mathcal V$-enriched $\infty$-categories to $\mathcal W$-enriched $\infty$-categories in the sense of Gepner--Haugseng. We prove this as part of a general-purpose interaction with the Boardman--Vogt tensor product $\otimes$: given a construction that takes an $\mathcal E$-monoidal $\infty$-category to a category expressible in diagrammatic terms, we give a criterion for it to take $(\mathcal{O} \otimes \mathcal{E})$-monoidal $\infty$-categories to $\mathcal{O}$-monoidal $\infty$-categories using a "pointwise" monoidal structure.
