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: "models and termination of proof reduction in the λπ calculus modulo theory"
  Abstract: We define a notion of model for the $\lambda \Pi$-calculus modulo#R##N#theory, a notion of super-consistent theory, and prove that#R##N#proof-reduction terminates in the $\lambda \Pi$-calculus modulo a#R##N#super-consistent theory. We prove this way the termination of#R##N#proof-reduction in two theories in the $\lambda \Pi$-calculus modulo#R##N#theory, and their consistency: an embedding of Simple type theory and#R##N#an embedding of the Calculus of constructions.
