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 notions of termination"
  Abstract: Five algebraic notions of termination are formalised, analysed and compared:#N#wellfoundedness or Noetherity, L\"ob's formula, absence of infinite iteration,#N#absence of divergence and normalisation. The study is based on modal semirings,#N#which are additively idempotent semirings with forward and backward modal#N#operators. To model infinite behaviours, idempotent semirings are extended to#N#divergence semirings, divergence Kleene algebras and omega algebras. The#N#resulting notions and techniques are used in calculational proofs of classical#N#theorems of rewriting theory. These applications show that modal semirings are#N#powerful tools for reasoning algebraically about the finite and infinite#N#dynamics of programs and transition systems.
