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 "on some exponential sums related to the coulter s polynomial"):
  Abstract: In this paper, the formulas of some exponential sums over finite field, related to the Coulter's polynomial, are settled based on the Coulter's theorems on Weil sums, which may have potential application in the construction of linear codes with few weights.

Includes members:
  Member "on the dual of the coulter matthews bent functions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "new classes of ternary bent functions from the coulter matthews bent functions")
  Member "complete weight enumerators of two classes of linear codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "complete weight enumerators of a class of linear codes with two or three weights")
  Member "linear codes with two or three weights from weakly regular bent functions":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "minimal linear codes constructed from functions")
  Member "a class of two weight and three weight codes and their applications in secret sharing":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "weight distributions and weight hierarchies of two classes of binary linear codes")
