下载 "Beyond the Mandelbrot set, an intro to holomorphic dynamics"

An intro to holomorphic dynamics, the study of iterated complex functions. Video on Newton's fractal: https://www.youtube.com/watch?v=-RdOwhmqP5s Special thanks to these supporters: https://www.3blue1brown.com//lessons/holomorphic-dynamics Extra special thanks to Sergey Shemyakov, of Aix-Marseille University, for helpful conversations and for introducing me to this phenomenon. Introduction to Fatou sets and Julia sets, including a discussion of Montel's theorem and its consequences: http://www.math.stonybrook.edu/~scott/Papers/India/Fatou-Julia.pdf Numberphile with Ben Sparks on the Mandelbrot set: https://www.youtube.com/watch?v=FFftmWSzgmk Ben explains how he made the Geogebra files on his channel here: https://www.youtube.com/watch?v=ICqj7nJbiRI (part 1) https://www.youtube.com/watch?v=3BXoNOahFJk (part 2) Excellent article on Acko.net, from the basics of building up complex numbers to Julia sets. https://acko.net/blog/how-to-fold-a-julia-fractal/ Bit of a side note, but if you want an exceedingly beautiful rendering of the quaternion-version of Julia fractals, take a look at this Inigo Quilez video: https://www.youtube.com/watch?v=rQ2bnU4dkso I first saw Fatou's theorem in this article: https://projecteuclid.org/journals/communications-in-mathematical-physics/volume-91/issue-2/On-the-iteration-of-a-rational-function--computer-experiments/cmp/1103940533.pdf Moduli spaces of Newton maps: https://arxiv.org/pdf/1512.05098.pdf On Montel's theorem: https://people.ucsc.edu/~fmonard/Sp17_Math207/lecture11.pdf On Newton's Fractal: https://core.ac.uk/download/pdf/1633889.pdf Thanks to these viewers for their contributions to translations Hebrew: Omer Tuchfeld ------------------ These animations are largely made using a custom python library, manim.
