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 "aligned image sets and the generalized degrees of freedom of symmetric mimo interference channel with partial csit"):
  Abstract: The generalized degrees of freedom (GDoF) of the two user symmetric multiple input multiple output (MIMO) interference channel (IC) are characterized as a function of the channel strength levels and the level of channel state information at the transmitters (CSIT). In this symmetric setting, each transmitter is equipped with M antennas, each receiver is equipped with N antennas, and both cross links have the same strength parameter $\alpha$ and the same channel uncertainty parameter $\beta$. The main challenge resides in the proof of the outer bound which is accomplished by a generalization of the aligned image sets approach.
