Component-count conjecture for positive definite singularities
Component-count conjecture for positive definite singularities
Let be a real function singularity of type , and let a versal deformation of have discriminant variety in its parameter space. The virtual morsifications of are grouped into seven virtual components.
component conjecture. Each of the seven virtual components is represented by exactly one connected component of the complement of the discriminant variety of any versal deformation of .
The preceding proposition establishes the seven virtual components and their total number of virtual morsifications. The conjecture asserts that no two virtual components are realized in the same discriminant-complement component and that all seven are realized.
