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 "several classes of permutation trinomials from niho exponents"):
  Abstract: Motivated by recent results on the constructions of permutation polynomials with few terms over the finite field \({\mathbb F}_{2^n}\), where n is a positive even integer, we focus on the construction of permutation trinomials over \({\mathbb F}_{2^n}\) from Niho exponents. As a consequence, several new classes of permutation trinomials over \({\mathbb F}_{2^n}\) are constructed from Niho exponents based on some subtle manipulation of solving equations with low degrees over finite fields.

Includes members:
  Member "new classes of permutation binomials and permutation trinomials over finite fields":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "some results about permutation properties of a kind of binomials over finite fields")
  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")
