human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "on completeness of reducibility candidates as a semantics of strong normalization"
  Abstract: This paper defines a sound and complete semantic criterion, based on#N#reducibility candidates, for strong normalization of theories expressed in#N#minimal deduction modulo \`a la Curry. The use of Curry-style proof-terms#N#allows to build this criterion on the classic notion of pre-Heyting algebras#N#and makes that criterion concern all theories expressed in minimal deduction#N#modulo. Compared to using Church-style proof-terms, this method provides both a#N#simpler definition of the criterion and a simpler proof of its completeness.
