Abstract
We give two characterisations of when a map-germ admits a 1-parameter stable unfolding, one related to the -codimension and another related to the normal form of a versal unfolding. We then prove that there are infinitely many finitely determined map-germs of multiplicity 4 from to which do not admit a 1-parameter stable unfolding.
