human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "upper bounds on the relative entropy and r enyi divergence as a function of total variation distance for finite alphabets"
  Abstract: A new upper bound on the relative entropy is derived as a function of the total variation distance for probability measures defined on a common finite alphabet. The bound improves a previously reported bound by Csisz\'ar and Talata. It is further extended to an upper bound on the R\'enyi divergence of an arbitrary non-negative order (including $\infty$) as a function of the total variation distance.

Connected through hyperedge HE-1 (induced by source paper "on the renyi divergence joint range of relative entropies and a channel coding theorem"):
