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 "generalized pair weights of linear codes and macwilliams extension theorem"):
  Abstract: In this paper, we introduce the notion of generalized pair weights of an $[n, k]$-linear code over a finite field and the notion of pair $r$-equiweight codes, where $1\le r\le k-1$. We give some properties of generalized pair weights of linear codes over finite fields. We obtain a necessary and sufficient condition for an $[n,k]$-linear code to be a pair equiweight code and characterize the pair $r$-equiweight codes for any $1\le r\le k-1$. In addition, a relationship between the pair equiweight code and the pair $r$-equiweight code is also given. Finally, we prove the MacWilliams extension theorem for the pair weight case.
