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: "algebraic proof complexity progress frontiers and challenges"
  Abstract: We survey recent progress in the proof complexity of strong proof systems and its connection to algebraic circuit complexity, showing how the synergy between the two gives rise to new approaches to fundamental open questions, solutions to old problems, and new directions of research. In particular, we focus on tight connections between proof complexity lower bounds (namely, lower bounds on the size of proofs of certain tautologies), algebraic circuit lower bounds, and the Polynomial Identity Testing problem from derandomization theory.

Connected through hyperedge HE-1 (induced by source paper "semi algebraic proofs ips lower bounds and the tau conjecture can a natural number be negative"):
  with members:
    - "proof complexity lower bounds from algebraic circuit complexity"
    - "characterizing propositional proofs as non commutative formulas"
    - "communication lower bounds via critical block sensitivity"
    - "hypercontractivity sum of squares proofs and their applications"
    - "approximability and proof complexity"
