The shape of the M in the MO-Labs-Logo is quite special and closely related to the subject of this blog. It belongs to a surface with a so-called cusp singularity, sometimes also called A4-singularity.
Singularities of surfaces are very special points. In most parts of a surface, the shape looks quite smooth, but in some it might not; such points are likely to be singularities.
The particular shape of the surface depicted in our logo is determined by the equation \(x^2-y^2=z^5\). Actually, the logo only shows its silhouette which is essentially the intersection of the surface with the plane \(y=0\), namely the plane curve \(x^2=z^5\):
