Asymptotic behavior of $T$-periodic solutions of singularly perturbed second-order differential equation

Abstract: We examine the asymptotic behavior of $T$-periodic solutions of the singularly perturbed differential equation $y"=f(t,y)$ as a small parameter $\u$ tends to zero.

Keywords: singularly perturbed equation, $T$-periodic solution
