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 complexity of matrix multiplication developments since 2014 extended abstract of 2018 oberwolfach complexity meeting plenary lecture"):
  Abstract: This is an overview of recent developments regarding the complexity of matrix multiplication, with an emphasis on the uses of algebraic geometry and representation theory in complexity theory.

Includes members:
  Member "further limitations of the known approaches for matrix multiplication":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "barriers for rectangular matrix multiplication")
  Member "powers of tensors and fast matrix multiplication":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "new algorithms and hardness for incremental single source shortest paths in directed graphs")
  Member "equations for lower bounds on border rank":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "on algebraic branching programs of small width")
  Member "new lower bounds for the rank of matrix multiplication":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "designing strassen s algorithm")
  Member "new lower bounds for the border rank of matrix multiplication":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "variety membership testing algebraic natural proofs and geometric complexity theory")
  Member "tensor rank some lower and upper bounds":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "learning representations from imperfect time series data via tensor rank regularization")
