Abstract

In this work we study a condition of non-degeneracy on analytic maps (R_n; 0) \to (R_n; 0) using the language of Newton polyhedra. When f:(R_n; 0) \to (R_n; 0) satisfies this condition and f^{-1}(0) = {0} , we obtain a result on the invariance of the local index of f under the summation of suitable monomials to each component function of f.
