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 "a new point of np hardness for 2 to 1 label cover"):
  Abstract: We show that given a satisfiable instance of the 2-to-1 Label Cover problem, it is NP-hard to find a $(23/24 + \eps)$-satisfying assignment.

Includes members:
  Member "rounding semidefinite programming hierarchies via global correlation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "new dependencies of hierarchies in polynomial optimization")
  Member "lasserre hierarchy higher eigenvalues and approximation schemes for quadratic integer programming with psd objectives":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "approximation limits of linear programs beyond hierarchies")
  Member "improved inapproximability results for maximum k colorable subgraph":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "the maximum binary tree problem")
  Member "approximation resistant predicates from pairwise independence":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "on the approximability of presidential type predicates")
  Member "conditional hardness for approximate coloring":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "the generalized orthogonality dimension of generalized kneser graphs bounds and applications")
