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: "triangular decomposition of matrices in a domain"
  Abstract: Deterministic recursive algorithms for the computation of matrix triangular decompositions with permutations like LU and Bruhat decomposition are presented for the case of commutative domains. This decomposition can be considered as a generalization of LU and Bruhat decompositions because they both may easily be obtained from this triangular decomposition. Algorithms have 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"
    - "generalized bruhat decomposition in commutative domains"
    - "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"
