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 "rooted divergence preserving branching bisimilarity is a congruence"):
  Abstract: We prove that rooted divergence-preserving branching bisimilarity is a congruence for the process specification language consisting of $\mathbf{0}$, action prefix, choice, and the recursion construct $\mu X.\_$.

Includes members:
  Member "sequential composition in the presence of intermediate termination extended abstract":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "divide and congruence iii from decomposition of modal formulas to preservation of stability and divergence")
  Member "lean and full congruence formats for recursion":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "failure trace semantics for a process algebra with time outs preliminary report")
  Member "on the executability of interactive computation":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "sequential composition in the presence of intermediate termination extended abstract")
  Member "computation tree logic with deadlock detection":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "divide and congruence iii from decomposition of modal formulas to preservation of stability and divergence")
  Member "branching bisimilarity with explicit divergence":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "ensuring liveness properties of distributed systems open problems")
