Abstract: | We study the existence of T-periodic solutions for the forced system of differential equations –ÿ= V(y)+h(t), where h is T-periodic and V is defined in an open, bounded and convex subset of RN and V – as y tends to the boundary of the set. We prove existence of at least one solution only requiring convexity of V near the boundary.Supported by Ministero Pubblica Istruzione, Gruppo Nazionale (40%) Calcolo delle Variazioni![rdquo](/content/nr545886028qp706/xxlarge8221.gif) |
