On periodic solutions of superquadratic Hamiltonian systems
We study the existence of periodic solutions for some Hamiltonian systems $dot z=JH_{z}(t,z)$ under new superquadratic conditions which cover the case $H(t,z)=|z|^{2}(ln (1+|z|^{p}))^q $ with $p, q>1$. By using the linking theorem, we obtain some new results.
