Abstract

We study the existence of homoclinic type solutions for second order Lagrangian systems of the type $$q̈(t)-q(t)+a(t)\nabla G(q(t))=f(t)$$, where $$t$$ $$\varepsilon$$ $$\Bbb R$$, $$q$$ $$\varepsilon$$ $$\Bbb R^n$$, $$a:\Bbb R \longrightarrow \Bbb R^n$$ is a continuous positive bounded function, $$G: \Bbb R^n \longrightarrow \Bbb R$$ is a $$C^1$$-smooth potential satisfying the Ambrosetti-Rabinowitz superquadratic growth condition and $$f:\Bbb R \longrightarrow \Bbb R^n$$ is a continuous bounded square integrable forcing term. A homoclinic type solution is obtained as limit of $$2k$$-periodic solutions of an approximative sequence of second order differential equations.
