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 "non deterministic kleene coalgebras"):
  Abstract: htmlabstractIn this paper, we present a systematic way of deriving (1) languages of (generalised)#R##N#regular expressions, and (2) sound and complete axiomatizations thereof, for a wide#R##N#variety of systems. This generalizes both the results of Kleene (on regular languages and deterministic#R##N#finite automata) and Milner (on regular behaviours and finite labelled transition#R##N#systems), and includes many other systems such as Mealy and Moore machines.

Includes members:
  Member "relating coalgebraic notions of bisimulation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "infinite types infinite data infinite interaction")
  Member "coalgebraic automata theory basic results":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "some model theory for the modal mu calculus syntactic characterisations of semantic properties")

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
