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 duality between exceptions and states"):
  Abstract: In this short note we study the semantics of two basic computational effects, exceptions and states, from a new point of view. In the handling of exceptions we dissociate the control from the elementary operation which recovers from the exception. In this way it becomes apparent that there is a duality, in the categorical sense, between exceptions and states.

Includes members:
  Member "certified proofs in programs involving exceptions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "imp with exceptions over decorated logic")
  Member "formal verification in coq of program properties involving the global state effect":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "imp with exceptions over decorated logic")
  Member "bases as coalgebras":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a typedriven vector semantics for ellipsis with anaphora using lambek calculus with limited contraction")
  Member "states and exceptions considered as dual effects":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "decorated proofs for computational effects states")
