Abstract
Let K be a field. A polynomial map K n → K n is power linear of degree d if it is of the form X + H = (X 1 + H 1,…, X n + H n ), where is a linear form in X 1,…, X n and d > 1. In this paper it is proved that if K is a field of characteristic not dividing d and F is a power linear polynomial map of degree d with nilpotency index two, i.e., (JH)2 = 0, then there exists a linear invertible polynomial map Φ such that Φ−1 FΦ is a triangular power linear map of degree d.
