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 "extension complexity of the correlation polytope"):
  Abstract: We prove that for every $n$-vertex graph $G$, the extension complexity of the correlation polytope of $G$ is $2^{O(\mathrm{tw}(G) + \log n)}$, where $\mathrm{tw}(G)$ is the treewidth of $G$. Our main result is that this bound is tight for graphs contained in minor-closed classes.

Includes members:
  Member "improved bounds for the excluded grid theorem":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "theta triangle free and even hole k_4 free graphs part 1 layered wheels")
  Member "extension complexity of independent set polytopes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "lifting with simple gadgets and applications to circuit and proof complexity")
  Member "communication complexity for algorithm designers":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "complexity theory game theory and economics the barbados lectures")
  Member "extended formulation for csp that is compact for instances of bounded treewidth":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "the complexity of general valued csps seen from the other side")
  Member "polynomial bounds for the grid minor theorem":
    also connected through other hyperedges:
