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 "on the number of minimal separators in graphs"):
  Abstract: We consider the largest number of minimal separators a graph on n vertices can have at most. #R##N#We give a new proof that this number is in $O( ((1+\sqrt{5})/2)^n n )$. #R##N#We prove that this number is in $\omega( 1.4521^n )$, improving on the previous best lower bound of $\Omega(3^{n/3}) \subseteq \omega( 1.4422^n )$. #R##N#This gives also an improved lower bound on the number of potential maximal cliques in a graph. We would like to emphasize that our proofs are short, simple, and elementary.
