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 "some open problems related to creative telescoping"):
  Abstract: Creative telescoping is the method of choice for obtaining information about definite sums or integrals. It has been intensively studied since the early 1990s, and can now be considered as a classical technique in computer algebra. At the same time, it is still subject of ongoing research. In this paper, we present a selection of open problems in this context. We would be curious to hear about any substantial progress on any of these problems.

Includes members:
  Member "efficient algorithms for mixed creative telscoping":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "linear differential equations as a data structure")
