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 "functional decomposition using principal subfields"):
  Abstract: Let f ∈ K(t) be a univariate rational function. It is well known that any non-trivial decomposition g o h, with g,h ∈ K(t), corresponds to a non-trivial subfield K(f(t)) ⊊ L ⊊ K(t) and vice-versa. In this paper we use the idea of principal subfields and fast subfield-intersection techniques to compute the subfield lattice of K(t)/K(f(t)). This yields a Las Vegas type algorithm with improved complexity and better run times for finding all non-equivalent complete decompositions of f.

Includes members:
