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: "probabilistic verification of all languages"
  Abstract: We present three protocols for verifying all languages: (i) For any unary (binary) language, there is a log-space (linear-space) interactive proof system (IPS); (ii) for any language, there is a constant-space weak-IPS (the non-members may not be rejected with high probability); and, (iii) for any language, there is a constant-space IPS with two provers where the verifier reads the input once. Additionally, we show that uncountably many binary (unary) languages can be verified in constant space and in linear (quadratic) expected time.

Connected through hyperedge HE-1 (induced by source paper "uncountable classical and quantum complexity classes"):
  with members:
    - "postselecting probabilistic finite state recognizers and verifiers"
    - "uncountable realtime probabilistic classes"
    - "automata and quantum computing"
    - "magic coins are useful for small space quantum machines"
    - "quantum stochastic and pseudo stochastic languages with few states"
    - "quantum finite automata a modern introduction"
    - "new results on the minimum amount of useful space"
    - "proving the power of postselection"
