Categorical and metric density

2025-12-02

Speaker: Tom Leinster (The University of Edinburgh, Scotland)

When metric spaces are viewed as enriched categories, the categorical notion of density does not coincide with the ordinary topological notion. This prompts two questions.First, what does categorical density mean for metric spaces? And second, does the condition of topological density...

On the commuting tensor product of symmetric multicategories and their bimodules

2026-01-13

Speaker: Nicola Gambino (University of Manchester, UK )

We provide a unified treatment of several commuting tensor products considered in the literature, including the tensor product of enriched categories and the Boardman-Vogt tensor product of symmetric multicategories, subsuming work of Elmendorf and Mandell. We then show how a commuting...
