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 a few weights trace codes over mathbb f _ q u mathbb f _ q"
  Abstract: Let $p$ be a prime number, $q=p^s$ for a positive integer $s$. For any positive divisor $e$ of $q-1$, we construct an infinite family codes of size $q^{2m}$ with few Lee-weight. These codes are defined as trace codes over the ring $R=\mathbb{F}_q + u\mathbb{F}_q$, $u^2 = 0$. Using Gauss sums, their Lee weight distributions are provided. When $\gcd(e,m)=1$, we obtain an infinite family of two-weight codes over the finite field $\mathbb{F}_q$ which meet the Griesmer bound. Moreover, when $\gcd(e,m)=2, 3$ or $4$ we construct new infinite family codes with at most five-weight.

Connected through hyperedge HE-1 (induced by source paper "a class of linear codes with few weights"):
  with members:
    - "new classes of p ary few weights codes"
