document: Harmless delays in Cohen-Grossberg neural networks Without assuming monotonicity and differentiability of the activation functions and any symmetry of interconnections , we establish some sufficient conditions for the globally asymptotic stability of a unique equilibrium for the Cohen-Grossberg -LRB- 1983 -RRB- neural network with multiple delays . Lyapunov functionals and functions combined with the Razumikhin technique are employed . The criteria are all independent of the magnitudes of the delays , and thus the delays under these conditions are harmless
