human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "the complexity of linear time temporal logic over the class of ordinals"):
  Abstract: We consider the temporal logic with since and until modalities. This temporal#N#logic is expressively equivalent over the class of ordinals to first-order#N#logic by Kamp's theorem. We show that it has a PSPACE-complete satisfiability#N#problem over the class of ordinals. Among the consequences of our proof, we#N#show that given the code of some countable ordinal alpha and a formula, we can#N#decide in PSPACE whether the formula has a model over alpha. In order to show#N#these results, we introduce a class of simple ordinal automata, as expressive#N#as B\"uchi ordinal automata. The PSPACE upper bound for the satisfiability#N#problem of the temporal logic is obtained through a reduction to the#N#nonemptiness problem for the simple ordinal automata.
