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 "a trivial yet optimal solution to vertex fault tolerant spanners"):
  Abstract: We give a short and easy upper bound on the worst-case size of fault tolerant spanners, which improves on all prior work and is fully optimal at least in the setting of vertex faults.

Includes members:
  Member "preserving distances in very faulty graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "approximate distance oracles subject to multiple vertex failures")
  Member "optimal vertex fault tolerant spanners for fixed stretch":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "approximate distance oracles subject to multiple vertex failures")
  Member "the greedy spanner is existentially optimal":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a polynomial time algorithm for almost optimal vertex fault tolerant spanners")
  Member "a hierarchy of lower bounds for sublinear additive spanners":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "exponentially faster shortest paths in the congested clique")
  Member "compact and fast sensitivity oracles for single source distances":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "generic single edge fault tolerant exact distance oracle")
  Member "dual failure resilient bfs structure":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "approximate distance oracles subject to multiple vertex failures")
  Member "the 4 3 additive spanner exponent is tight":
    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "weighted additive spanners")
  Member "fault tolerant approximate bfs structures":
    also connected through other hyperedges:
      - Hyperedge HE-8 (induced by source paper "approximate distance oracles subject to multiple vertex failures")
