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: "a short note on two variable logic with a linear order successor and a preorder successor"
  Abstract: The finite satisfiability problem of two-variable logic extended by a linear order successor and a preorder successor is shown to be undecidable.

Connected through hyperedge HE-1 (induced by source paper "logics for word transductions with synthesis"):
  with members:
    - "the first reactive synthesis competition syntcomp 2014"
    - "on reversible transducers"
    - "on equivalence and uniformisation problems for finite transducers"
    - "regular combinators for string transformations"
    - "synthesis of deterministic top down tree transducers from automatic tree relations"
    - "transducers with origin information"
    - "two variable logic with two order relations"
    - "mso definable string transductions and two way finite state transducers"

Connected through hyperedge HE-2 (induced by source paper "decidable logics for transductions and data words"):
  with members:
    - "transducers with origin information"
    - "two variable logic with two order relations"
