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: "on streams that are finitely red"
  Abstract: Mixing induction and coinduction, we study alternative definitions of streams#N#being finitely red. We organize our definitions into a hierarchy including also#N#some well-known alternatives in intuitionistic analysis. The hierarchy#N#collapses classically, but is intuitionistically of strictly decreasing#N#strength. We characterize the differences in strength in a precise way by weak#N#instances of the Law of Excluded Middle.
