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 "decorated proofs for computational effects states"):
  Abstract: The syntax of an imperative language does not mention explicitly the state, while its denotational semantics has to mention it. In this paper we show that the equational proofs about an imperative language may hide the state, in the same way as the syntax does.

Includes members:
  Member "a duality between exceptions and states":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "imp with exceptions over decorated logic")
  Member "adjunctions for exceptions":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "scalability using effects")
  Member "a duality between exceptions and states":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "imp with exceptions over decorated logic")
  Member "states and exceptions considered as dual effects":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "a duality between exceptions and states")
  Member "cartesian effect categories are freyd categories":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "certified proofs in programs involving exceptions")
