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 "well possedness of the continuous neighborhood filter and its reformulation through the decreasing rearrangement"):
  Abstract: We study the existence and uniqueness of solutions of a time-continuous version of the Neighborhood filter. In the line of previous works [12, 13, 14], we reformulate the usual pixel-based version of the filter introducing functional rearrangements, which are shown to be useful both for the filter analysis and for its fast implementation.

Includes members:
  Member "on a fast bilateral filtering formulation using functional rearrangements":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "well posedness of a nonlinear integro differential problem and its rearranged formulation")
  Member "neighborhood filters and the decreasing rearrangement":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on a fast bilateral filtering formulation using functional rearrangements")

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).
