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 "computing the lambert w function in arbitrary precision complex interval arithmetic"):
  Abstract: We describe an algorithm to evaluate all the complex branches of the Lambert W function with rigorous error bounds in interval arithmetic, which has been implemented in the Arb library. The classic 1996 paper on the Lambert W function by Corless et al. provides a thorough but partly heuristic numerical analysis which needs to be complemented with some explicit inequalities and practical observations about managing precision and branch cuts.

Includes members:
  Member "arb efficient arbitrary precision midpoint radius interval arithmetic":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "fungrim a symbolic library for special functions")
  Member "efficient implementation of elementary functions in the medium precision range":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "numerical evaluation of elliptic functions elliptic integrals and modular forms")
  Member "lambert w function for applications in physics":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "analysis and optimization of loss functions for multiclass top k and multilabel classification")
