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: "explicit tensors of border rank at least 2n 1"
  Abstract: For odd n, I write down tensors in C^n\otimes C^n\otimes C^n of border rank 2n-1, showing the non-triviality of the Young-flattening equations of Landsberg-Ottaviani. I also study the border rank of the tensors of Alexeev et. al., showing the tensors their tensors T_{2^k}, despite having rank equal to 2^{k+1}-1, have border rank equal to 2^k, the minimum of any concise tensor. I also study the equations of Griesser.

Connected through hyperedge HE-1 (induced by source paper "equations for lower bounds on border rank"):
  with members:
    - "explicit lower bounds via geometric complexity theory"
    - "new lower bounds for the border rank of matrix multiplication"

Connected through hyperedge HE-2 (induced by source paper "new lower bounds for the border rank of matrix multiplication"):
  with members:
    - "powers of tensors and fast matrix multiplication"
    - "equations for lower bounds on border rank"
    - "explicit lower bounds via geometric complexity theory"
    - "new lower bounds for the rank of matrix multiplication"
