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: "an introduction to algebraic geometry codes"
  Abstract: We present an introduction to the theory of algebraic geometry codes. Starting from evaluation codes and codes from order and weight functions, special attention is given to one-point codes and, in particular, to the family of Castle codes.

Connected through hyperedge HE-1 (induced by source paper "locally recoverable codes from algebraic curves with separated variables"):
  with members:
    - "optimal lrc codes for all lenghts n q"
    - "some contributions to the construction of locally recoverable codes from algebraic curves"
    - "locally recoverable codes on algebraic curves"
    - "a family of optimal locally recoverable codes"
    - "on the locality of codeword symbols"

Connected through hyperedge HE-2 (induced by source paper "quantum error correcting codes from algebraic geometry codes of castle type"):
  with members:
    - "stabilizer quantum codes from j affine variety codes and a new steane like enlargement"
    - "quantum codes from affine variety codes and their subfield subcodes"
    - "quantum stabilizer codes from maximal curves"
    - "euclidean and hermitian self orthogonal algebraic geometry codes and their application to quantum codes"
    - "on the order bounds for one point ag codes"
