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 "stochastic parity games on lossy channel systems"):
  Abstract: We give an algorithm for solving stochastic parity games with almost-sure winning conditions on lossy channel systems, under the constraint that both players are restricted to finitememory strategi ...

Includes members:
  Member "solving stochastic b uchi games on infinite arenas with a finite attractor":
    also connected through other hyperedges:
      (none)
  Member "recursive concurrent stochastic games":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "how good is a strategy in a game with nature")
  Member "verifying nondeterministic probabilistic channel systems against ω regular linear time properties":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "parity objectives in countable mdps")
  Member "decisive markov chains":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "decisiveness of stochastic systems and its application to hybrid models")
  Member "the existential theory of equations with rational constraints in free groups is pspace complete":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "word equations in linear space")
