human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "theory presentation combinators"):
  Abstract: We motivate and give semantics to theory presentation combinators as the foundational building blocks for a scalable library of theories. The key observation is that the category of contexts and fibered categories are the ideal theoretical tools for this purpose.

Includes members:
  Member "the mathscheme library some preliminary experiments":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "building on the diamonds between theories theory presentation combinators")
  Member "type classes for mathematics in type theory":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "tabled typeclass resolution")
  Member "nonuniform coercions via unification hints":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "deciding kleene algebras in coq")
  Member "a scalable module system":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "building on the diamonds between theories theory presentation combinators")
  Member "on duplication in mathematical repositories":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "building on the diamonds between theories theory presentation combinators")
  Member "parsimony principles for software components and metalanguages":
    also connected through other hyperedges:
      (none)
