Abstract: In this paper ,we are concerned with the existence of positive periodic solutions to the differential equations with state-dependent delay x′(t) = −A(t, x(t))x(t) + B(x(t))F(x(t − (t, x(t)))). Using Krasnoselskii fixed point theorem, we establish some sufficient condition for the existence and nonexistence of positive !-periodic solutions to the above equation .
Key words: Differential equtions, Positive periodic solution, Fixed point theorem, State- dependent
