Thus far in the factorization homology learning seminar, we have primarily discussed factorization homology of E_n-algebras (informally referred to as "factorization homology alpha"). For E_n-algebras in spaces, this admits a generalization to (∞,n)-categories (informally referred to as "factorization homology beta"). In the case that n=1, this has been extended further to enriched (∞,1)-categories.

 

In this talk, I will carefully explain both factorization homology beta and enriched factorization homology in dimension 1. I will also discuss its functoriality, leading to the cyclotomic structure on topological Hochschild homology (THH). Along the way, we'll see various familiar combinatorially-defined categories (such as Connes's cyclic category) arising naturally within the context of manifold topology.

 

This represents various joint works among David Ayala, John Francis, Nick Rozenblyum, and myself.
