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: "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"
  Abstract: We construct an infinite family of two-Lee-weight and three-Lee-weight codes over the non-chain ring $\mathbb{F}_p+u\mathbb{F}_p+v\mathbb{F}_p+uv\mathbb{F}_p,$ where $u^2=0,v^2=0,uv=vu.$ These codes are defined as trace codes. They have the algebraic structure of abelian codes. Their Lee weight distribution is computed by using Gauss sums. With a linear Gray map, we obtain a class of abelian three-weight codes and two-weight codes over $\mathbb{F}_p$. In particular, the two-weight codes we describe are shown to be optimal by application of the Griesmer bound. We also discuss their dual Lee distance. 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:
    - "trace codes with few weights over mathbb f _p u 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"
