Abstract: ABSTRACT: Conditions are given for a Ck map T to be a Newton map, that is, the map associated with a differentiable realvalued function via Newton’s method. For finitely differentiable maps and functions, these conditions are only necessary, but in the smooth case, that is, for k= ∞, they are also sufficient. The characterisation rests upon the structure of the fixed point set of T and the value of the derivative T' there, and it is best possible as is demonstrated through examples
