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 "set theoretic completeness for epistemic and conditional logic"):
  Abstract: The standard approach to logic in the literature in philosophy and mathematics, which has also been adopted in computer science, is to define a language (the syntax), an appropriate class of models together with an interpretation of formulas in the language (the semantics), a collection of axioms and rules of inference characterizing reasoning (the proof theory), and then relate the proof theory to the semantics via soundness and completeness results. Here we consider an approach that is more common in the economics literature, which works purely at the semantic, set-theoretic level. We provide set-theoretic completeness results for a number of epistemic and conditional logics, and contrast the expressive power of the syntactic and set-theoretic approaches

Includes members:
  Member "defining relative likelihood in partially ordered preferential structures":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "weighted regret based likelihood a new approach to describing uncertainty")
  Member "nonmonotonic reasoning preferential models and cumulative logics":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the existence of characterization logics and fundamental properties of argumentation semantics")
  Member "plausibility measures and default reasoning":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a reconstruction of the multipreference closure")
