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 "weighted gaussian entropy and determinant inequalities"):
  Abstract: We produce a series of results extending information-theoretical inequalities (discussed by Dembo--Cover--Thomas in 1989-1991) to a weighted version of entropy. The resulting inequalities involve the Gaussian weighted entropy; they imply a number of new relations for determinants of positive-definite matrices.

Includes members:
  Member "entropy power inequality for weighted entropy":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "basic inequalities for weighted entropies")
  Member "an extension of the ky fan inequality":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "results on the solutions of maximum weighted renyi entropy problems")
  Member "simple inequalities for weighted entropies":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "asymptotic behaviour of weighted differential entropies in a bayesian problem")
