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 "interference cooperation and connectivity a degrees of freedom perspective"):
  Abstract: We explore the interplay between interference, cooperation and connectivity in heterogeneous wireless interference networks. Specifically, we consider a 4-user locally-connected interference network with pairwise clustered decoding and show that its degrees of freedom (DoF) are bounded above by 12 over 5. Interestingly, when compared to the corresponding fully connected setting which is known to have 8 over 3 DoF, the locally connected network is only missing interference-carrying links, but still has lower DoF, i.e., eliminating these interference-carrying links reduces the DoF. The 12 over 5 DoF outer bound is obtained through a novel approach that translates insights from interference alignment over linear vector spaces into corresponding sub-modularity relationships between entropy functions.

Includes members:
  Member "index coding via linear programming":

    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "noma an information theoretic perspective")
