Periodic solutions for planar systems with time-varying delays
Electronic journal of differential equations, Tome 2005 (2005)
This paper concerns delay differential systems that can be regarded as a model of two-neuron artificial neural network with delayed feedback. Some interesting results are obtained for the existence of a periodic solution for the system. Our approach is based on the continuation theorem of coincidence degree, and a-priori estimates of the periodic solutions.
