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 sphere packing bound via augustin s method"):
  Abstract: The channel coding problem is reviewed for an abstract framework and a sufficient condition for the strong converse property is provided. A sphere packing bound (SPB) with a polynomial prefactor is established for the decay rate of the error probability with the block length on any sequence of product channels $\{{W}_{[1,n]}\}_{n\in\mathbb{Z}^{+}}$ satisfying $\max_{t\leq n} C_{0.5,{W}_{t}}=\mathit{O}(\ln n)$, by first establishing a non-asymptotic SPB. For the discrete stationary product channels with feedback, the sphere packing exponent is proved to bound the exponential decay rate of the error probability with the block length from above, by first establishing a non-asymptotic SPB. The result for the channels with feedback continues to hold for the product channels with feedback satisfying a milder stationarity hypothesis. A non-asymptotic SPB with a polynomial prefactor is established for various Poisson channels.
