Global existence of periodic solutions in a simplified four-neuron BAM neural network model with multiple delays

<p>We consider a simplified bidirectional associated memory (BAM) neural network model with four neurons and multiple time delays. The global existence of periodic solutions bifurcating from Hopf bifurcations is investigated by applying the global Hopf bifurcation theorem due to Wu and Bendixs...
