Remarks on Forced Oscillations on Manifolds

Proceedings of the Steklov Institute of Mathematics
In this paper the author studied the existence of forced oscillations on a manifold in the presence of dissipation in the system, also the existence of forced oscillations in systems without dissipation in the case when the driving force is small.

Forced oscillations in a rotating liquid (II)

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1962
Der vorliegenden Analyse liegen die linearisierten Gleichungen fur die achsensymmetrischen Storungen einer gleichformig rotierenden Flussigkeit zugrunde. Dabei wird aber keine Annahme hinsichtlich einer Zeitabhangigkeit der erzwungenen Bewegungen gemacht und die Entwicklung der Storungen vom Beginn der erzwungenen Bewegung an studiert.

Forced oscillations in piezoelectric crystals.

2002
The author proves existence and uniqueness of weak solutions to a hyperbolic-elliptic system of PDEs, whichs models forced oscillations in a piezoelectric viscoelastic body. The system consists of a linear dissipative second order hyperbolic system (for the elastic displacement) and a linear second-order elliptic equation (for the electric potential ...

On forced oscillations of Lagrangian systems

1986
We study the existence of infinitely many periodic solutions of the Lagrangian system $\frac{d}{dt}\frac{\partial\mathcal{\mathfrak{L}}}{\partial\dot{q}}$-$\frac{\text{\ensuremath{\partial}}\mathcal{\mathfrak{L}}}{\partial q}$+ f(t) = 0 (where f(t) is a periodic «forcing» term). We assume that the potential «grows» superquadratically at infinity.
