“…Nevertheless, not all SDDEs are stable with exponential decay rate, there also exist a great number of SDDEs are actually stable but obeying a certain lower decay rate except exponential decay rate. We mention here [2,29,34,33,3,43,18,16,30,45] among others. For example, Zhang and Chen [43] and Liu et al [18] discussed the pth moment and almost sure stability with general decay rate of highly nonlinear hybrid SDDEs and hybrid neutral SDDEs (NSDDEs) with time-varying coefficients, respectively.…”
