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 parameterized complexity of graph modification to first order logic properties"):
  Abstract: We consider the problems of deciding whether an input graph can be modified by removing/adding at most $k$ vertices/edges such that the result of the modification satisfies some property definable in first-order logic. We establish a number of sufficient and necessary conditions on the quantification pattern of the first-order formula $\phi$ for the problem to be fixed-parameter tractable or to admit a polynomial kernel.

Includes members:
  Member "kernelization lower bounds by cross composition":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "subexponential parameterized algorithms and kernelization on almost chordal graphs")
  Member "on the non existence of polynomial kernels for p l free edge modification problems":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "faster and enhanced inclusion minimal cograph completion")
  Member "deciding first order properties of locally tree decomposable structures":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "hitting topological minors is fpt")
