M-deformations of $\cal {A}$-simple $\Sigma^{n-p+1}$-germs from $\bb {R}^n$ to $\bb {R}^p$, $n\ge p

All $\cal {A}$-simple singularities of map-germs from $\bb {R}^n$ to $\bb {R}^p$, where $n\ge p$, of minimal corank (i.e. of corank $n-p+1$) have an M-deformation, that is a deformation in which the maximal numbers of isolated stable singular points are simultaneously present in the discriminant.
