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 "skew generalized cyclic code over r x_1 sigma_1 delta_1 x_2 sigma_2 delta_2"):
  Abstract: This article studies two dimensional skew generalized cyclic (SGC) codes, i.e., SGC codes over the ring $ R[x_1;\sigma_1,\delta_1][x_2;\sigma_2,\delta_2]$, where $R$ is a ring with unity. Here, we discuss the structural properties of SGC codes, and a sufficient number of examples of MDS codes are given to show the importance of our results. Also, we improve BCH lower bounds for the minimum distance of SGC codes with non-zero derivation.

Includes members:
  Member "some properties of skew codes over finite fields":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "skew polynomial rings and skew cyclic codes")
  Member "dual codes of product semi linear codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a note on the duals of skew constacyclic codes")
