Abstract

In this paper I discuss schematically a few aspects of the dynamical evolution of spiral galaxies.

Galactic structures, like spirals, bars etc., show clear signs of dynamical evolution within a few galactic rotation periods. Furthermore they will generate secular evolution of the axisymmetric background. Thus stationary solutions can only be considered as a first approximation.
