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 "mimo z interference channels capacity under strong and noisy interference"):
  Abstract: The capacity regions of multiple-input multiple-output Gaussian Z-interference channels are established for the very strong interference and aligned strong interference cases. The sum-rate capacity of such channels is established under noisy interference. These results generalize known results for scalar Gaussian Z-interference channels.

Includes members:
  Member "capacity regions and sum rate capacities of vector gaussian interference channels":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "signal processing and optimal resource allocation for the interference channel")
  Member "noisy interference sum rate capacity of parallel gaussian interference channels":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "ergodic fading interference channels sum capacity and separability")
  Member "a new outer bound and the noisy interference sum rate capacity for gaussian interference channels":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "vector gaussian successive refinement with degraded side information")
