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: "fixed parameter inapproximability for clique and setcover in time super exponential in opt"
  Abstract: In this paper, we consider proving inapproximability in terms of OPT and thus we base the foundations of fixed parameter inapproximability.

Connected through hyperedge HE-1 (induced by source paper "from gap eth to fpt inapproximability clique dominating set and more"):
  with members:
    - "completely inapproximable monotone and antimonotone parameterized problems"
    - "almost polynomial ratio eth hardness of approximating densest k subgraph"
    - "a birthday repetition theorem and complexity of approximating dense csps"
    - "how to refute a random csp"
    - "time approximation trade offs for inapproximable problems"
    - "eth hardness for densest k subgraph with perfect completeness"
    - "the constant inapproximability of the parameterized dominating set problem"
    - "lower bounds on the size of semidefinite programming relaxations"

Connected through hyperedge HE-2 (induced by source paper "the constant inapproximability of the parameterized dominating set problem"):
  with members:
    - "completely inapproximable monotone and antimonotone parameterized problems"
    - "the parameterized complexity of k biclique"
    - "deciding first order properties of nowhere dense graphs"
    - "analytical approach to parallel repetition"
    - "fixed parameter and approximation algorithms a new look"
