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 "upper and lower bounds on the minimum distance of expander codes"):
  Abstract: The minimum distance of expander codes over GF(q) is studied. A new upper bound on the minimum distance of expander codes is derived. The bound is shown to lie under the Varshamov-Gilbert (VG) bound while q >= 32. Lower bounds on the minimum distance of some families of expander codes are obtained. A lower bound on the minimum distance of low-density parity-check (LDPC) codes with a Reed--Solomon constituent code over GF(q) is obtained. The bound is shown to be very close to the VG bound and to lie above the upper bound for expander codes.

Includes members:
  Member "improved nearly mds expander codes":

      - Hyperedge HE-1 (induced by source paper "linear time erasure list decoding of expander codes")
  Member "distance properties of expander codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "linear time erasure list decoding of expander codes")
