human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "generalized bruhat decomposition in commutative domains"
  Abstract: Deterministic recursive algorithms for the computation of generalized Bruhat decomposition of the matrix in commutative domain are presented. This method has the same complexity as the algorithm of matrix multiplication.

Connected through hyperedge HE-1 (induced by source paper "recursive matrix algorithms in commutative domain for cluster with distributed memory"):
  with members:
    - "recursive method for the solution of systems of linear equations"
    - "time and space efficient generators for quasiseparable matrices"
    - "triangular decomposition of matrices in a domain"
    - "simultaneous computation of the row and column rank profiles"
    - "fast generalized bruhat decomposition"
    - "algorithms for the solution of systems of linear equations in commutative rings"

Connected through hyperedge HE-2 (induced by source paper "fast computation of the rank profile matrix and the generalized bruhat decomposition"):
  with members:
    - "computing the rank profile matrix"
    - "parallel computation of echelon forms"
    - "simultaneous computation of the row and column rank profiles"
    - "fast matrix rank algorithms and applications"
    - "rank profile revealing gaussian elimination and the cup matrix decomposition"
