Second order nonautonomous systems with symmetric potential changing sign
In this paper we deal with the problem of multiplicity of periodic solutions for a class of nonautonomous second order Hamiltonian systems, having indefinite potential. In the particular case that the quadratic part of the potential is negative definite, one reaches a result of subharmonic and homoc...
