On the fractal characteristics of a stabilised Newton method

Drexler, Michael and Sobey, Ian and Bracher, C. (1995) On the fractal characteristics of a stabilised Newton method. Technical Report. Unspecified. (Submitted)



In this report, we present a complete theory for the fractal that is obtained when applying Newton's Method to find the roots of a complex cubic. We show that a modified Newton's Method improves convergence and does not yield a fractal, but basins of attraction with smooth borders. Extensions to higher-order polynomials and the numerical relevance of this fractal analysis are discussed.
