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: "deadlock detection in linear recursive programs"
  Abstract: Deadlock detection in recursive programs that admit dynamic resource creation is extremely complex and solutions either give imprecise answers or do not scale. #R##N#We define an algorithm for detecting deadlocks of "linear recursive programs" of a basic model. The theory that underpins the algorithm is a generalization of the theory of permutations of names to so-called "mutations", which transform tuples by introducing duplicates and fresh names. #R##N#Our algorithm realizes the back-end of deadlock analyzers for object-oriented programming languages, once the association programs/basic-model-programs has been defined as front-end.
