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 diversity multiplexing tradeoff of the symmetric mimo half duplex relay channel"):
  Abstract: This paper has been withdrawn due to an error in one of the equations in the extended portion.

Includes members:
  Member "the diversity multiplexing tradeoff of the dynamic decode and forward protocol on a mimo half duplex relay channel":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "energy efficient resource allocation in machine to machine communications with multiple access and energy harvesting for iot")
  Member "diversity multiplexing tradeoff for the mimo static half duplex relay":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "diversity of linear transceivers in mimo af half duplex relaying channels")
  Member "diversity multiplexing tradeoff of the half duplex relay channel":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "when are dynamic relaying strategies necessary in half duplex wireless networks")
  Member "on the achievable diversity multiplexing tradeoffs in half duplex cooperative channels":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "algebraic fast decodable relay codes for distributed communications")
