Hochschild functor conjecture for enriched categories and bimodules
Hochschild functor conjecture for enriched categories and bimodules
Let be a presentably symmetric monoidal -category. Let be the -category whose objects are -enriched categories and whose morphisms are bimodules. There is a Hochschild construction . Hochschild functor conjecture. There exists a functor of -categories
Moreover, if is closed symmetric monoidal, then is a -enriched functor of -enriched -categories. This would supply the Hochschild shadow in the important case of enriched categories and bimodules; the source does not state whether the claim has been proved or remains open.
