Factorization algebras are local-to-global objects living on manifolds, and they arise
naturally in mathematics and physics. Their local structure encompasses examples like …

These are notes from talks given at a spring school on topological quantum field theory in
Nova Scotia during May of 2023. The aim is to introduce the reader to the role of …

This short paper illustrates the general framework introduced in the paper “Not too little
discs”, joint with Victor Carmona, on yet another one dimensional example. It exhibits a …

We investigate the global structure of topological defects which wrap a submanifold $
F\subset M $ in a quantum field theory defined on a closed manifold $ M $. The Pontryagin …

We introduce the notions of linked space, linked quasi-category and linked manifold, which
are certain spans of the ordinary versions of the respective objects, and which model …
