Hamilton-Poisson realizations for the Lü system.
We establish Hartman-Wintner type criteria for the half-linear second order differential equation where this equation is viewed as a perturbation of another equation of the same form.
We consider general second order boundary value problems on the whole line of the type , , for which we provide existence, non-existence, multiplicity results. The solutions we find can be reviewed as heteroclinic orbits in the plane dynamical system.
We establish Hille-Wintner type comparison criteria for the half-linear second order differential equation where this equation is viewed as a perturbation of another equation of the same form.
