Abstract

We consider a mixed function of type H(\mathbf z, \mathbf z)=f(\mathbf z) g(\mathbf z) where f and g are convenient holomorphic functions which have isolated critical points at the origin and we assume that the intersection f=g=0 is a complete intersection variety with an isolated singlarity at theorigin. We assume also that H satisfies the multiplicity condition.We will show that H has a tubular Milnor fibration and also a spherical Milnor fibration. We give examples which does not satisfy the Newton multiplicity condition where one does not have Milnor fibration and the others have Milnor fibrations.
