Component-count conjecture for J103J_{10}^3 singularities

Let f0f_0 be a real function singularity of type J103J_{10}^3. Consider the discriminant variety in the parameter space of any versal deformation of f0f_0.

J103J_{10}^3 component conjecture. The complement of the discriminant variety has exactly 33 distinct components.

The preceding proposition describes 23 virtual components, their involution, and ten additional components obtained by reflection in a vertical mirror. The claim is that these constructions account for all actual components of the discriminant complement; the source also notes that topological-type invariants distinguish all but two pairs.
