(AM-144) Jacek Graczyk and Grzegorz Swiatek Shopping Cart Table of Contents In 1920, Pierre Fatou expressed the conjecture thatexcept for special casesall critical points of a rational map of the Riemann sphere tend to periodic orbits under iteration. This conjecture remains the main open problem in the dynamics of iterated maps. For the logistic family x- ax(1-x), it can be interpreted to mean that for a dense set of parameters "a," an attracting periodic orbit exists. The same question appears naturally in science, where the logistic family is used to construct models in physics, ecology, and economics. In this book, Jacek Graczyk and Grzegorz Swiatek provide a rigorous proof of the Real Fatou Conjecture. In spite of the apparently elementary nature of the problem, its solution requires advanced tools of complex analysis. The authors have written a self-contained and complete version of the argument, accessible to someone with no knowledge of complex dynamics and only basic familiarity with interval maps. The book will thus be useful to specialists in real dynamics as well as to graduate students. Table of Contents Series: Annals of Mathematics Studies Phillip A. Griffiths, John N.

Biography Base Home Link To Us Search Biographies: Browse Biographies A B C D ... Z Pierre Fatou Biography Pierre Fatou (28 February 1878 - 10 August 1929) was a French mathematician working in the field of complex analytic dynamics. He entered the École Normale Supérieure in Paris in 1898 to study mathematics and graduated in 1901 when he was appointed an astronomy post in the Paris Observatory. Fatou continued his mathematical explorations and studied iterative and recursive processes. Fatou was particularly interested in the case where Z0 = 0, which was later analysed with computers by Benoit Mandelbrot to generate graphical representations of the behaviour of this series for each point, c, in the complex plane - now popularly called the Mandelbrot set. If the series does not tend to infinity, it is in the Mandelbrot set otherwise it is not. Images of the set are typically coloured black where points are in the set and coloured according to the escape speed of the series where not. Each point in the complex plane also has an associated Julia set. There is a 1-1 correspondence between the points in the Mandelbrot set and the connected Julia sets. All points not in the Mandelbrot set have Julia sets that are not connected. Fatou wrote many papers developing a Fundamental theory of iteration in 1917, which he published in the December 1917 part of Comptes Rendus. His findings were very similar to those of Gaston Maurice Julia, who submitted a paper to the Académie des Sciences in Paris for their 1918 Grand Prix on the subject of iteration from a global point of view. Their work is now commonly referred to as the Generalised Fatou Julia theorem.

Prisoners and EscapeesJulia Sets Discussion Student: So the Mandelbrot set is made up of Julia sets , which are prisoner sets. What is a prisoner Mentor: That is a simplified description, but you have all the main ideas. Let's talk about Prisoners and Escapees , and Gaston Julia and Pierre Fatou. After World War I, Julia and Fatou were interested in iterating two variable (or complex) equations using recursion . They chose an equation and iterated it using various starting points. Mathematicians call this sort of problem a dynamical system . They found that if you looked at different starting points, different behaviors would emerge. Let's look at the simplest interesting case: f(Z) = Z^2 + C where C is any point (complex number) inside the circle of radius 2. We are only interested in those points because that is where we will be looking for the Mandelbrot set eventually. Here's an experiment to try: Let C = (0,0) and start with the point (0,1). What happens? Student: Let's see; Z = (0,1) f(0,1) = (0,1)^2 + (0,0) = (-1,0) + (0,0) = (-1,0)

Given a function f(x) and a starting value x one can construct a new value x =f(x ). With some persistence, the next value x is obtained by another application of f: x =f(x )=f(f(x )). This is an iterative process that, generally speaking, generates a sequence x , x , ... x k , ..., where x k is the k th iterate obtained by applying the function f to x k times. The sequence is known as an orbit of its starting point x . Gaston Julia (1893-1978) and Pierre Fatou (1878-1929) made a fundamental contribution to the study of iterative processes. Their contribution (Ref [3]), although regarded as a masterpiece, was largely ignored by the mathematical community until a revival in the late 1970s spawned by the discovery of fractals by Benoit Mandelbrot. For a given function f, behavior of an orbit very much depends on the selection of the starting point x . Following is a rough classification of possible behaviors: k =x p so that the sequence repeats itself Chaos k The set of points with chaotic orbits is called the Julia set for a given function f. Until quite recently the study of iterations and Julia sets has been in a prolonged limbo. B.Mandelbrot has the following to say on the development of the theory

I beg you pardon... Since english is not my mothers language, it easily is possible that you find rather strange expressions in this text. If you please would tell me such stuff (via mail) I would correct them at the next revision. Fatou Julia Mandelbrot Louis Pierre Joseph Fatou In 1915 the Académie des Sciences published the topic of her "Grand Prix" for 1918. It should be a study regarding Iterations. The Académie des Sciences hoped for a continuation on Montel’s concept about "normale (Abbildungs-)Familien". So Fatou wrote an extensive paper covering a fundamental theory about Iterations. One assumes his intention to take part at this "Grand prix". Nobody was astonished, that other mathematicians took part, since the question had been published. So Gaston Julia developed the same theory on a very similar base. Later it was obvious that these two mathematicians worked on the very same problem going a different way. When submitting the two papers some strange things happened, it is difficult to see there the light. Seemingly Fatou did not participate at the contest, but anyway, later he was honored. It seems that Fatou did not really treat fractals, but he prepared basics for the researches of Julia and Mandelbrot. Nevertheless, Julia sets from outside the Mandelbrot set are called "Fatou Dust". My Julia-programm allows to draw such structures, but since it dyes values between maximum and minimum, these "dusts" do not appear as lots of separated spots.

Fatou Julia Mandelbrot Louis Pierre Joseph Fatou 1915 gab die Académie des Sciences in Paris das Thema ihres "Grand Prix" für 1918 bekannt. Der Preis sollte für eine Studie über das Thema Iterationen verliehen werden, da sich die Académie des Sciences davon eine Weiterentwicklung von Montel's Konzept "normaler (Abbildungs-)Familien" erhoffte. Fatou schrieb 1917 einen langen Aufsatz, um die fundamentale Theorie der Iteration zu entwickeln. Obwohl man nicht sicher weiss, ob Fatou beabsichtigte, am Grand Prix teilzunehmen, vermutet man dies. Da das Thema des Grand Prix bekannt war, ist es nicht verwunderlich, dass auch andere Mathematiker dieser Zeit in diesem Themengebiet arbeiteten. So entwickelte Gaston Julia die gleiche Theorie auf eine ähnliche Art und Weise. Fatou scheint sich nicht speziell um Fraktale gekümmert zu haben, er hat vielmehr Grundlagen für die späteren Arbeiten von Julia und Mandelbrot erarbeitet. Ihm zu Ehren nennt man Julia-Figuren aus Bereichen ausserhalb der Mandelbrot-Menge "Fatou-Staub". Ich kann solche Gebilde mit meinem Julia-Programm auch erzeugen, nur zerfallen sie nicht unbedingt zu einer Vielzahl von Flecken, weil mein Programm auch Werte zwischen Maximum und Minimum einfärbt. Fatou Julia Mandelbrot Gaston Maurice Julia Es sollte eine Zeit der schlimmsten Schmerzen werden, und da vergrub er sich - wohl um sich etwas abzulenken - in ein mathematisches Problem: Es war das Verhalten der Funktion, die hinter den Julia-Figuren steckt. Nach seiner Entlassung aus dem Lazarett - der Krieg war in der Zwischenzeit beendet - veröffentlichte er ein ca. 200 Seiten starkes Buch "Mémoire sur l'iteration des fonctions rationelles".

The application of mathematics to predict the way that things behave is crucial to our attempts to understand problems like how the weather changes over periods of days or of decades, how ecological balances might be affected by sudden changes in human activity, how economies will change when financial policies are altered, how to optimise the braking system of a car, how to assess risk, how turbulent air flows around an aircraft wing, or how close to Earth an approaching asteroid might pass.

Fractals Nikos Salingaros (NS) : For the past few years, I have been applying the analytic thinking of a scientist to find basic laws for architecture and urbanism, following the lead of my friend, the brilliant architectural theorist Christopher Alexander. The results derived so far show that a building, or city, is subject to the same organizational laws as a biological organism and a complex computer program. The New Architecture depends upon scientific rules rather than stylistic dictates. Using these rules, we can create new buildings that duplicate the intensely positive, nourishing feelings of the greatest historical buildings, without copying neither their form nor their style.
