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 "termination of triangular integer loops is decidable"):
  Abstract: We consider the problem whether termination of affine integer loops is decidable. Since Tiwari conjectured decidability in 2004, only special cases have been solved. We complement this work by proving decidability for the case that the update matrix is triangular.

Includes members:
  Member "t2 temporal property verification":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "control flow refinement by partial evaluation and its application to termination and cost analysis")
  Member "on termination of integer linear loops":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a calculus for modular loop acceleration")
  Member "deciding conditional termination":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a calculus for modular loop acceleration")
