human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "trace codes with few weights over mathbb f _p u mathbb f _p"
  Abstract: We construct an infinite family of two-Lee-weight and three-Lee-weight codes over the chain ring $\mathbb{F}_p+u\mathbb{F}_p.$ They have the algebraic structure of abelian codes. Their Lee weight distribution is computed by using Gauss sums. Then by using a linear Gray map, we obtain an infinite family of abelian codes with few weights over $\mathbb{F}_p$. In particular, we obtain an infinite family of two-weight codes which meets the Griesmer bound with equality. Finally, an application to secret sharing schemes is given.

Connected through hyperedge HE-1 (induced by source paper "new few weight codes from trace codes over a local ring"):
  with members:
    - "two weight and three weight codes from trace codes over mathbb f _p u mathbb f _p v mathbb f _p uv mathbb f _p"
    - "a class of q ary linear codes derived from irreducible cyclic codes"
    - "a class of two weight and three weight codes and their applications in secret sharing"
    - "hamming weights in irreducible cyclic codes"
