human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "coordination in multiagent systems and laplacian spectra of digraphs"
  Abstract: Constructing and studying distributed control systems requires the analysis of the Laplacian spectra and the forest structure of directed graphs. In this paper, we present some basic results of this analysis. We also discuss the application of these results published earlier to decentralized control and touch upon some problems of spectral graph theory.

Connected through hyperedge HE-1 (induced by source paper "the projection method for continuous time consensus seeking"):
  with members:
    - "the forest consensus theorem"
    - "the projection method for reaching consensus and the regularized power limit of a stochastic matrix"

Connected through hyperedge HE-2 (induced by source paper "the forest consensus theorem"):
  with members:
    - "the projection method for reaching consensus and the regularized power limit of a stochastic matrix"
    - "comments on consensus and cooperation in networked multi agent systems"
