The Agrarian Question in Kenya
The condition Y < a indicates that the point u is in a homofocal ellipse inside this
first ellipse. We thus establish Meiners Theorem. Yhe expaneion (4s; is valid for

The Stability of Solar System and of Small Stellar Systems
In order to handle the problem more easily, we take a discrete family of
homofocal ellipses as a model. The iterated point is supposed to jump from one
ellipse to the next one. In fact, this problem reduces itself to a one-dimensional
gambler's ...
