Center node: "construction of mds self dual codes over finite fields"
  Abstract: In this paper, we obtain some new results on the existence of MDS self-dual codes utilizing (extended) generalized Reed-Solomon codes over finite fields of odd characteristic. For some fixed $q$, our results can produce more classes of MDS self-dual codes than previous works.

Connected through hyperedge HE-1 (induced by source paper "two classes of new mds self dual codes over finite fields"):
  with members:
    - "new mds self dual codes over finite fields of odd characteristic"
    - "new mds self dual codes from generalized reed solomon codes"

Connected through hyperedge HE-2 (induced by source paper "an unified approach on constructing of mds self dual codes via reed solomon codes"):
  with members:
    - "new mds self dual codes from generalized reed solomon codes"

Connected through hyperedge HE-3 (induced by source paper "on the constructions of mds self dual codes via cyclotomy"):
  with members:
    - "new mds self dual codes from generalized reed solomon codes"

Connected through hyperedge HE-4 (induced by source paper "new mds self dual codes over finite fields of odd characteristic"):
  with members:

    - "new mds euclidean and hermitian self dual codes over finite fields"
