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 "refinement types as higher order dependency pairs"):
  Abstract: Refinement types are a well-studied manner of performing in-depth analysis on functional programs. The dependency pair method is a very powerful method used to prove termination of rewrite systems; however its extension to higher order rewrite systems is still the object of active research. We observe that a variant of refinement types allow us to express a form of higher-order dependency pair criterion that only uses information at the type level, and we prove the correctness of this criterion.

Includes members:
  Member "static dependency pair method based on strong computability for higher order rewrite systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a static higher order dependency pair framework")
  Member "on the relation between size based termination and semantic labelling":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "size based termination of higher order rewriting")
  Member "semi continuous sized types and termination":
    also connected through other hyperedges:
