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: "computability on the countable ordinals and the hausdorff kuratowski theorem"
  Abstract: In this note, we explore various potential representations of the set of countable ordinals. An equivalence class of representations is then suggested as a standard, as it offers the desired closure properties. With a decent notion of computability on the space of countable ordinals in place, we can then state and prove a computable uniform version of the Hausdorff-Kuratowski theorem.

Connected through hyperedge HE-1 (induced by source paper "a topological view on algebraic computation models"):
  with members:
    - "on the algebraic structure of weihrauch degrees"
    - "representations of analytic functions and weihrauch degrees"
    - "comparing representations for function spaces in computable analysis"
    - "weihrauch completeness for layerwise computability"
    - "non deterministic computation and the jayne rogers theorem"
    - "the degree structure of weihrauch reducibility"
    - "real analytic machines and degrees"
    - "noncomputable functions in the blum shub smale model"
