Subharmonic solutions for nonautonomous second-order Hamiltonian systems
In this article, we prove the existence of subharmonic solutions for the non-autonomous second-order Hamiltonian system $ddot{u}(t)+V'(t,u(t))=0$. Also we study the minimality of their periods, when the nonlinearity $V'(t,x)$ grows faster than $|x|^{alpha}$, $alphain[0,1[$ at infinity...
