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 "synchrony vs causality in the asynchronous pi calculus"):
  Abstract: We study the relation between process calculi that differ in their either synchronous or asynchronous interaction mechanism. Concretely, we are interested in the conditions under which synchronous interaction can be implemented using just asynchronous interactions in the p-calculus. We assume a number of minimal conditions referring to the work of Gorla: a “good” encoding must be compositional and preserve and reflect computations, deadlocks, divergence, and success. Under these conditions, we show that it is not possible to encode synchronous interactions without introducing additional causal dependencies in the translation.

Includes members:
  Member "synchrony vs causality in asynchronous petri nets":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on characterising distributability")
  Member "comparing the expressive power of the synchronous and asynchronous pi calculi":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "comparing process calculi using encodings")
