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 "distribution of the largest eigenvalue for real wishart and gaussian random matrices and a simple approximation for the tracy widom distribution"):
  Abstract: We derive efficient recursive formulas giving the exact distribution of the largest eigenvalue for finite dimensional real Wishart matrices and for the Gaussian Orthogonal Ensemble (GOE). In comparing the exact distribution with the limiting distribution of large random matrices, we also found that the Tracy–Widom law can be approximated by a properly scaled and shifted gamma distribution, with great accuracy for the values of common interest in statistical applications.

Includes members:
  Member "mimo networks the effects of interference":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "how much bandpass filtering is required in massive mimo base stations")
  Member "condition numbers of gaussian random matrices":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "toward a theory of optimization for over parameterized systems of non linear equations the lessons of deep learning")
  Member "performance analysis of mimo mrc in double correlated rayleigh environments":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "performance of two way relaying over α μ fading channels in hybrid rf fso wireless networks")
