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
all points u insifo the ellipse E uith fooii +l and -l, and ohich passes through the ...

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 ...

We can then proceed, as we shall do in the following case of the ellipsoid, by
utilizing the homofocal surfaces. Consider the ellipsoid 1222 ^• + ^ + ^--l = 0, a>b

Mathematical Evolutions
"You see, if some point M does not lie on the diagonal then, Figure 7 for e small
enough, it will be outside a homofocal ellipse. This means that the limit of the
homofocal ellipses is just the diagonal, in the form of all of its points, and no other
