Center node: "distributed storage systems based on equidistant subspace codes"
  Abstract: Distributed storage systems based on equidistant constant dimension codes are presented. These equidistant codes are based on the Pl\"{u}cker embedding, which is essential in the repair and the reconstruction algorithms. These systems posses several useful properties such as high failure resilience, minimum bandwidth, low storage, simple algebraic repair and reconstruction algorithms, good locality, and compatibility with small fields.

Connected through hyperedge HE-1 (induced by source paper "equidistant subspace codes"):
  with members:
    - "partial spreads in random network coding"
    - "an algebraic approach for decoding spread codes"
    - "spread codes and spread decoding in network coding"
    - "a rank metric approach to error control in random network coding"
    - "coding for errors and erasures in random network coding"
