Serie XXX, Nr 1

Models for illustration of the projective plane on an finite closed singularity-free surface. Surface with only three singularities.


Mathematical description
Surface introduced by Werner Boy in 1901. This shows the projective plane in the same way as the sphere shows the Imaginair numberplane. In short, the immersion of the real projective plane RP2 into R3 with self intersection. This plane has a maximum, a minimum and a hyperbolic paraboloid.
