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 "the stability of delaunay triangulations"):
  Abstract: We introduce a parametrized notion of genericity for Delaunay triangulations which, in particular, implies that the Delaunay simplices of δ-generic point sets are thick. Equipped with this notion, we study the stability of Delaunay triangulations under perturbations of the metric and of the vertex positions. We quantify the magnitude of the perturbations under which the Delaunay triangulation remains unchanged.

Includes members:
  Member "delaunay stability via perturbations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "delaunay simplices in diagonally distorted lattices")
  Member "delaunay triangulation of manifolds":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "persistent homology as stopping criterion for voronoi interpolation")
  Member "kinetic stable delaunay graphs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "stable delaunay graphs")
  Member "duals of orphan free anisotropic voronoi diagrams are triangulations":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "practical conditions for well behaved ness of anisotropic voronoi diagrams")
