Abstract
Given a non trivial power series in ℝm × ℝk, it is in general not possible to choose a good direction in ℝk in order to apply Weierstrass Preparation Theorem. Now, one can make it possible by blowing-up coefficients in ℝm. This enables e. g. to prove in some natural way Gabrielov’s complement theorem, as well as Gabrielov’s fiber components theorem in subanalytic geometry.
