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 "distributed resource allocation over a class of nonlinear multi agent systems"):
  Abstract: This paper investigates a resource allocation problem over a class of nonlinear multi-agent systems, which may be subject to unknown observation disturbances. We aim to drive the outputs of agent to the optimal resource allocation by using only local data and exchanged information from their neighbors. This problem can be taken as an extension of the existing distributed resource allocation problem for higher-order nonlinear agents. To solve this problem, a novel passivity-based analysis and design approach was presented, along with both asymptotic and exponential convergence results. The effectiveness of our design was verified by numerical examples.
