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: "complexity of a single face in an arrangement of s intersecting curves"
  Abstract: Consider a face F in an arrangement of n Jordan curves in the plane, no two of which intersect more than s times. We prove that the combinatorial complexity of F is O( s(n)), O( s+1(n)), and O( s+2(n)), when the curves are bi-innite, semi-innite, or bounded, respectively; k(n) is the maximum length of a Davenport-Schinzel sequence of order k on an alphabet of n symbols. Our bounds asymptotically match the known worst-case lower bounds. Our proof settles the still apparently open case of semi-innite curves. Moreover, it treats the three cases in a fairly uniform fashion.

Connected through hyperedge HE-1 (induced by source paper "sharp bounds on davenport schinzel sequences of every order"):
