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 "a sequent calculus and a theorem prover for standard conditional logics"):
  Abstract: In this paper we present a cut-free sequent calculus, called SeqS, for some standard conditional logics, namely CK, CK+ID, CK+MP and CK+MP+ID. The calculus uses labels and transition formulas and can be used to prove decidability and space complexity bounds for the respective logics. We also present CondLean, a theorem prover for these logics implementing SeqS calculi written in SICStus Prolog.

Includes members:
  Member "what does a conditional knowledge base entail":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a reconstruction of the multipreference closure")
  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 "belief revision a critique":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "aggregating learned probabilistic beliefs")
  Member "plausibility measures and default reasoning":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "a reconstruction of the multipreference closure")
