A note on a nonlinear functional differential system with feedback control
In this note we apply Avery-Peterson multiple fixed point theorem to investigate the existence of multiple positive periodic solutions to the following nonlinear non-autonomous functional differential system with feedback control \[\left\{\begin{array}{l} \frac{dx}{dt}=-r(t)x(t)+F(t,x_t,u(t-\delta(t...
