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 "new classes of permutation binomials and permutation trinomials over finite fields"):
  Abstract: Permutation polynomials over finite fields play important roles in finite fields theory. They also have wide applications in many areas of science and engineering such as coding theory, cryptography, combinatorial design, communication theory and so on. Permutation binomials and trinomials attract people's interest due to their simple algebraic form and additional extraordinary properties. In this paper, several new classes of permutation binomials and permutation trinomials are constructed. Some of these permutation polynomials are generalizations of known ones.

Includes members:
  Member "some new results on permutation polynomials over finite fields":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "new permutation trinomials constructed from fractional polynomials")
  Member "permutation trinomials over finite fields with even characteristic":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "some results about permutation properties of a kind of binomials over finite fields")
