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 permutation quadrinomials and 4 uniform bct"):
  Abstract: We study a class of general quadrinomials over the field of size $2^{2m}$ with odd $m$ and characterize conditions under which they are permutations with the best boomerang uniformity, a new and important parameter related to boomerang-style attacks. This vastly extends previous results from several recent papers.

Includes members:
  Member "new results about the boomerang uniformity of permutation polynomials":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "4 uniform bct permutations from generalized butterfly structure")
  Member "on a conjecture about a class of permutation quadrinomials":
    also connected through other hyperedges:
      (none)
  Member "solutions of x q k cdots x q x a in gf 2 n":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "4 uniform bct permutations from generalized butterfly structure")
  Member "differentially 4 uniform permutations with the best known nonlinearity from butterflies":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "4 uniform bct permutations from generalized butterfly structure")
  Member "a highly nonlinear differentially 4 uniform power mapping that permutes fields of even degree":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "on the differential linear connectivity table of vectorial boolean functions")
