Structured Cospans — John C. Baez & Kenny Courser (2019). arXiv:1911.04630 (v3, PDF); Theory and Applications of Categories, Vol. 35, 2020, No. 48, pp 1771-1822.
Introduces structured cospans for a left adjoint , obtaining hypergraph categories of open networks, which arise from symmetric monoidal double categories, and explains how they avoid technical problems of decorated cospans.
