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: "some new constructions of coded caching schemes with reduced subpacketization"
  Abstract: First, a new perspective based on binary matrices of placement delivery array (PDA) design was introduced, by which the PDA design problem can be simplified. From this new perspective, and based on some families of combinatorial designs, new schemes with low subpacketization for centralized coded caching problem were constructed. We also give a technique for constructing new coded caching scheme from known schemes based on direct product of PDAs.

Connected through hyperedge HE-1 (induced by source paper "subexponential and linear subpacketization coded caching via line graphs and projective geometry"):
  with members:
    - "a multi antenna coded caching scheme with linear subpacketization"
    - "decentralized coded caching without file splitting"
