The Nuclear Three-Body Problem, this deceptive simplicity and until the end of the 1970s believed that they had succeeded in giving a complete mathematical description of the structure of these galaxies. Ellipticals were then thought to be axially symmetric isothermal ensembles, increasingly flattened the more rapidly they rotate around their axis of symmetry.

https://doi.org/10.1007/b100519The majority of spiral galaxies are barred. How is the bar represented in the dynamics and evolution of these galaxies? The bar and the spiral are without doubt intimately linked, the bar possibly being the origin of the spiral wave (or vice versa). Why, then, are not all spiral galaxies barred?
