Existence of positive periodic solutions to nonlinear second order differential equations
In this paper, we discuss the existence of positive periodic solutions to the nonlinear differential equation u (t) + a(t)u(t) = f (t, u(t)), t R, where a : R [0, +) is an -periodic continuous function with a(t) 0, f : R
