Details of the hypergraph:
Center node: "the third order term in the normal approximation for the awgn channel"
  Abstract: This paper shows that, under the average error probability formalism, the third-order term in the normal approximation for the additive white Gaussian noise channel with a maximal or equal power constraint is at least    $({1}/{2})\log n\,+\,O(1)$   . This improves on the lower bound by Polyanskiys–Poor–Verdu (2010) and matches the upper bound proved by the same authors.
