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: "stabbing pairwise intersecting disks by five points"
  Abstract: We present an $O(n)$ expected time algorithm and an $O(n \log n)$ deterministic time algorithm to find a set of five points that stab a set of $n$ pairwise intersecting disks in the plane. We also give a simple construction with 13 pairwise intersecting disks that cannot be stabbed by three points.

Connected through hyperedge HE-1 (induced by source paper "efficiently stabbing convex polygons and variants of the hadwiger debrunner p q theorem"):
  with members:
    - "stabbing pairwise intersecting disks by four points"

Connected through hyperedge HE-2 (induced by source paper "on maximum sum matchings of points"):
  with members:
    - "stabbing pairwise intersecting disks by four points"
    - "matching colored points with rectangles"
    - "bichromatic compatible matchings"

Connected through hyperedge HE-3 (induced by source paper "eptas for max clique on disks and unit balls"):
  with members:
    - "on pseudo disk hypergraphs"
    - "optimal parameterized algorithms for planar facility location problems using voronoi diagrams"
    - "approximation and inapproximability results for maximum clique of disc graphs in high dimensions"
