Erzwingende Gleichung/Gerade/Beispiel/en

We consider the line (or etc.) with the (identical) function . For and , i.e. for the homogeneous equation , the geometric object consists of a horizontal line (corresponding to the zero-solution) and a vertical line over . So all fibers except one are zero-dimensional vector spaces. For the inhomogeneous equation , is a hyperbola, and all fibers are zero-dimensional with the exception that the fiber over is empty.

For the homogeneous equation , is just the affine cylinder over the base line. For the inhomogeneous equation , consists of one vertical line, almost all fibers are empty.
