Abstract

This article consists of two papers: Typical dynamics of Newton’s method\textit{Typical dynamics of Newton's method} by Steele and Erratum to "Typical dynamics of Newton’s method"\textit{Erratum to "Typical dynamics of Newton's method"} by Dud\'ak and Steele. Let C1(M)C^1(M) be the space of continuously differentiable real-valued functions defined on [M,M][-M,M]. We show that for the typical element ff in C1(M)C^1(M), there exists a set S[M,M]S \subseteq [-M,M], both residual and of full measure in [M,M][-M,M], such that for any xSx \in S, the trajectory generated by Newton's method using ff and xx either diverges, converges to a root of ff, or generates a Cantor set as its attractor. Whenever the Cantor set is the attractor, the dynamics on the attractor are described by a single type of adding machine, so that the dynamics on all of these attracting Cantor sets are topologically equivalent.
