Abstract: Cobordism categories describe the algebraic gluing structure of manifolds, and they are central in the functorial description of topological quantum field theories (TQFTs). We consider a new “nested” variation of a cobordism category where manifolds come with embedded submanifolds and cobordisms with subcobordisms. An example is the category of cylinders with lines. In this talk I will describe the algebraic structure associated with this striped cylinder cobordism category. This is joint work with Calle, Murray, Pacheco-Tallaj, Rovi and Sridhar-Shapiro.
