recommendations! Published in 2020 at "International Journal of Robust and Nonlinear Control"

DOI: 10.1002/rnc.5195

Abstract: In this article, exponential bipartite synchronization in mth moment of random signed networks is studied. Different from previous work, both random disturbances and Markovian switching are considered into signed networks. It is worth emphasizing that… read more here.
