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 "sensitivity to cumulative perturbations for a class of piecewise constant hybrid systems"):
  Abstract: We consider a class of continuous-time hybrid dynamical systems that correspond to subgradient flows of a piecewise linear and convex potential function with finitely many pieces, and which include the fluid-level dynamics of the Max-Weight scheduling policy as a special case. We study the effect of an external disturbance/perturbation on the state trajectory, and establish that the magnitude of this effect can be bounded by a constant multiple of the integral of the perturbation.

Includes members:
  Member "when do trajectories have bounded sensitivity to cumulative perturbations":
    also connected through other hyperedges:
      (none)
  Member "nonexpansive piecewise constant hybrid systems are conservative":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "when do trajectories have bounded sensitivity to cumulative perturbations")
  Member "fluctuation bounds for the max weight policy with applications to state space collapse":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "when do trajectories have bounded sensitivity to cumulative perturbations")
  Member "cone schedules for processing systems in fluctuating environments":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "when do trajectories have bounded sensitivity to cumulative perturbations")
