Kurzbeschreibung: The surface of a revolution of a circle of radius $b$ about a line in the plane of the circle at a distance $a$ from the centre of the circle is called a torus or ring surface; this is an algebraic surface of the degree four with the equation
$ (x^2 + y^2 + z^2 + a^2 - b^2) = 4a^2(x^2 + y^2)$
in a suitably chosen Cartesian coordinate system. We know three types of ring surfaces: …
