We compare the topology of the link $$L_0$$ L 0 of non-isolated singularities defined by real analytic map-germs $$({\mathbb {R}}^m,0) \buildrel {h} \over {\rightarrow } ({\mathbb {R}}^n,0)$$ ( R m , 0 ) → h ( R n , 0 ) , $$m > n$$ m > n , with that of the boundary of a local non-critical level of h. We show that if the germ of h has an isolated critical value at $$0 \in {\mathbb {R}}^n$$ 0 ∈ R n and admits a local Milnor-Lê fibration at 0, then there exists “a vanishing zone for h”. This is an appropriate neighborhood of the set $$L_0 \cap \Sigma $$ L 0 ∩ Σ , where $$\Sigma $$ Σ denotes the critical set of h, such that away from it the topology of $$L_0$$ L 0 is fully determined by the boundary of the corresponding local Milnor fibre. We give conditions for the vanishing zone to be a fiber bundle over $$L_0 \cap \Sigma $$ L 0 ∩ Σ . A particular class of real singularities we envisage in this paper are those of the type $$f\bar{g}: ({\mathbb {C}}^n,0) \rightarrow ({\mathbb {C}},0)$$ f g ¯ : ( C n , 0 ) → ( C , 0 ) with f, g holomorphic and satisfying certain conditions. We introduce for these a regularity criterium for having a local Milnor-Lê fibration, and we use this to produce an example of a real analytic singularity which does not have the Thom $$a_f$$ a f -property and yet has a local Milnor-Lê fibration. Throughout this work we provide explicit examples of functions satisfying the hypothesis we need in each section.
