For some authors, it seems that hypergraphs allow or do not allow edges on edges, but it's hard to find a lot of literature on the topic. I am wondering if hypergraphs with edges on edges had a specific name, or what to look for in literature.
Also, I can see this kind of recursive structures in other areas of maths, the first two that comes to mind being:
- Higher categories with (n+1) morphisms on (n) morphisms
- Polytopes with (n+1)-dimensional faces built upon (n)-dimensional faces (3D cell -> 2D faces -> 1D edge -> 0D vertex)
My questions are:
- Is there any literature on hypergraphs with edges on edges?
- Do they have a specific name?
- Is there any general abstraction for recursive structures in maths like hypergraphs with edges on edges/higher categories/polytopes?
