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 "graph theoretic characterization of the feasibility of the precoding based 3 unicast interference alignment scheme"):
  Abstract: A new precoding-based intersession network coding (NC) scheme has recently been proposed, which applies the interference alignment technique, originally devised for wireless interference channels, to the 3-unicast problem of directed acyclic networks. The main result of this work is a graph-theoretic characterization of the feasibility of the 3-unicast interference alignment scheme. To that end, we first investigate several key relationships between the point-to-point network channel gains and the underlying graph structure. Such relationships turn out to be critical when characterizing graph-theoretically the feasibility of precoding-based solutions.

Includes members:
  Member "on the feasibility of precoding based network alignment for three unicast sessions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "multi server coded caching")
  Member "on the relation between the index coding and the network coding problems":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "embedded index coding")
