1304.1325 (Matej Pavšič)

Pais-Uhlenbeck Oscillator with Benign Friction Force    [PDF]

Matej Pavšič
It is shown that the Pais-Uhlenbeck oscillator with damping, considered by Nesterenko, is a special case of a more general oscillator that has not only a first order, but also a third order friction term. If the corresponding damping constants, $\alpha$ and $\beta$, are both positive and below certain critical values, then the system is stable. In particular, if $\alpha =-\beta$, then we have the unstable Nesterenko's oscillator
