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 "fully abstract game semantics for actors"):
  Abstract: Based on the work on the algebraic theory of actors and game semantics for asynchronous $\pi$ calculus, we give the full abstraction proof of game semantics for actors.

Includes members:
  Member "full abstraction for fair testing in ccs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an intensionally fully abstract sheaf model for pi expanded version")
  Member "games and full completeness for multiplicative linear logic":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "interaction laws of monads and comonads")
  Member "innocent strategies as presheaves and interactive equivalences for ccs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "bisimulation maps in presheaf categories")
  Member "asynchronous games innocence without alternation":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "what s in a game a theory of game models")
  Member "sequentiality vs concurrency in games and logic":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "what s in a game a theory of game models")
