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 "a combinatorial approach for the state complexity of the shuffle product"):
  Abstract: We investigate the state complexity of the shuffle operation on regular languages initiated by Campeanu et al. and studied subsequently by Brzozowski et al. We shift the problem into the combinatorics domain by turning the problem of state accessibility into a problem of intersection of partitions. This allows us to develop new tools and to reformulate the conjecture of Brzozowski et al. about the above-mentionned state complexity.

Includes members:
  Member "a general approach to state complexity of operations formalization and limitations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "algebraic and combinatorial tools for state complexity application to the star xor problem")
  Member "on the state complexity of the shuffle of regular languages":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "algebraic and combinatorial tools for state complexity application to the star xor problem")
