Samuel Lattès
Samuel Lattès (21 February 1873 (Nice) – 5 July 1918) was a French mathematician. From 1892 to 1895 he studied at the École Normale Superieure. After this he was a teacher in Algiers, Dijon and Nice. After a promotion to Paris in 1906 he moved first to Montpellier in 1908 and then to Besançon, before he took up a professorship at the University of Toulouse in 1911. He died of typhus in 1918. Today Lattès is best known for his work on complex sets, particularly for examples of rational functions including the Riemann sphere in its Julia set. Today these examples are described as Lattès maps or Lattès examples.Für eine moderne Darstellung der Lattèsschen Beispiele und neuere Ergebnisse dazu siehe: John Milnor, ''On Lattès maps''.

In mathematics, a Lattès map is a rational map ''f'' = Θ''L''Θ−1 from the complex sphere to itself such that Θ is a holomorphic map from a complex torus In mathematics, a complex torus is a particular kind of complex manifold ''M'' whose underlying smooth manifold is a torus in the usual sense (i.e. the cartesian product of some number ''N'' circles). Here ''N'' must be the even number 2''n'', whe ... to the complex sphere and ''L'' is an affine map ''z'' → ''az'' + ''b'' from the complex torus to itself.

Michèle Audin
Michèle Audin (Algiers, 3 January, 1954) is a French mathematician, writer, and a former professor. She has worked as a professor at the University of Geneva, the University of Paris-Saclay and most recently at the University of Strasbourg, where she performed research notably in the area of symplectic geometry. Biography Michéle Audin is the daughter of mathematician Maurice Audin and mathematics teacher , both pied-noirs and political activists for the independence of Algeria. While she was a child, her father died under torture in June 1957 in Algeria, after being arrested by General Jacques Massu's paratroopers. She studied at the École normale supérieure de jeunes filles (now merged into the École Normale Supérieure but at the time a separate institution) and then she earned a Ph.D. degree in 1986 from the University of Paris-Saclay, with a thesis written under the supervision of François Latour, entitled ''Cobordismes d'immersions lagrangiennes et legendriens'' obo ...

Gaston Julia
Gaston Maurice Julia (3 February 1893 – 19 March 1978) was a French mathematician who devised the formula for the Julia set. His works were popularized by Benoit Mandelbrot; the Julia and Mandelbrot fractals are closely related. He founded, independently with Pierre Fatou, the modern theory of holomorphic dynamics. Military service Julia was born in the Algerian town of Sidi Bel Abbes, at the time governed by the French. During his youth, he had an interest in mathematics and music. His studies were interrupted at the age of 21, when France became involved in World War I and Julia was conscripted to serve with the army. During an attack he suffered a severe injury, losing his nose. His many operations to remedy the situation were all unsuccessful, and for the rest of his life he resigned himself to wearing a leather strap around the area where his nose had been. Career in mathematics Julia gained attention for his mathematical work at the age of 25, in 1918, when his 199-pag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Fatou
Pierre Joseph Louis Fatou (28 February 1878 – 9 August 1929) was a French mathematician and astronomer. He is known for major contributions to several branches of mathematical analysis, analysis. The Fatou lemma and the Fatou set are named after him. Biography Pierre Fatou's parents were Prosper Ernest Fatou (1832-1891) and Louise Eulalie Courbet (1844-1911), both of whom were in the military. Pierre's family would have liked for him to enter the military as well, but his health was not sufficiently good for him to pursue a military career. Fatou entered the École Normale Supérieure in Paris in 1898 to study mathematics and graduated in 1901 when he was appointed an intern (''stagiaire'') in the Paris Observatory. Fatou was promoted to assistant astronomer in 1904 and to astronomer (''astronome titulaire'') in 1928. He worked in this observatory until his death. Fatou was awarded the Henri Becquerel, Becquerel prize in 1918; he was a knight of the Legion of Honour (1923). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Milnor
John Willard Milnor (born February 20, 1931) is an American mathematician known for his work in differential topology, algebraic K-theory and low-dimensional holomorphic dynamical systems. Milnor is a distinguished professor at Stony Brook University and the only mathematician to have won the Fields Medal, the Wolf Prize, the Abel Prize and all three Steele prizes. Early life and career Milnor was born on February 20, 1931, in Orange, New Jersey. His father was J. Willard Milnor, an engineer, and his mother was Emily Cox Milnor. As an undergraduate at Princeton University he was named a Putnam Fellow in 1949 and 1950 and also proved the Fáry–Milnor theorem when he was only 19 years old. Milnor graduated with an A.B. in mathematics in 1951 after completing a senior thesis, titled "Link groups", under the supervision of Ralph Fox. He remained at Princeton to pursue graduate studies and received his Ph.D. in mathematics in 1954 after completing a doctoral dissertation, t ...

Julia Set
In complex dynamics, the Julia set and the Classification of Fatou components, Fatou set are two complement set, complementary sets (Julia "laces" and Fatou "dusts") defined from a function (mathematics), function. Informally, the Fatou set of the function consists of values with the property that all nearby values behave similarly under iterated function, repeated iteration of the function, and the Julia set consists of values such that an arbitrarily small Perturbation theory, perturbation can cause drastic changes in the sequence of iterated function values. Thus the behavior of the function on the Fatou set is "regular", while on the Julia set its behavior is "chaos theory, chaotic". The Julia set of a function is commonly denoted \operatorname(f), and the Fatou set is denoted \operatorname(f). These sets are named after the French mathematicians Gaston Julia and Pierre Fatou whose work began the study of complex dynamics during the early 20th century. Form ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...
