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: "well pointed coalgebras"
  Abstract: For endofunctors of varieties preserving intersections, a new description of#N#the final coalgebra and the initial algebra is presented: the former consists#N#of all well-pointed coalgebras. These are the pointed coalgebras having no#N#proper subobject and no proper quotient. The initial algebra consists of all#N#well-pointed coalgebras that are well-founded in the sense of Osius and Taylor.#N#And initial algebras are precisely the final well-founded coalgebras. Finally,#N#the initial iterative algebra consists of all finite well-pointed coalgebras.#N#Numerous examples are discussed e.g. automata, graphs, and labeled transition#N#systems.
