“…Remark 2 If we set σ (t, e(t, x), e(t − τ (t), x)) = 0, the synchronization problem for reaction-diffusion neural networks without stochastic perturbation has been studied in [7,11,20,34,37,41]. However, the results of these are not presented in terms of LMIs, which makes their checking by the developed algorithms somewhat difficult and inconvenient.…”
