Abstract: | We propose in this paper a significant refinement of normal forms for differentiable maps near a fixed point. We give a method
to obtain further reduction of classical normal forms with concrete and interesting applications. Our method leads to unique
normal forms either with respect to general diffeomorphisms in certain cases or with respect to near identity diffeomorphisms
in other cases. Our approach is rational in the sense that if the coefficients of a map are in a field K, so is its normal form.
