Boy's Surface

The Boy’s Surface is a family of surfaces. Werner Boy, in his dissertation under Hilbert, constructed an immersion of the projective plane. Boy’s Surface has besides its self-intersection curves only one more serious singularity, namely a triple point. His construction was topological. Apéry found algebraically embedded “Boy’s Surfaces”. The Bryant-Kusner Boy’s Surfaces are obtained by an inversion from a minimal surface.
