Felix Hausdorff Felix Hausdorff (1913-1921) Felix Hausdorff 8 november 26 januari ) was een Duitse wiskundige die als een van de stichters van de moderne topologie wordt beschouwd en als iemand die een grote bijdrage heeft geleverd aan de verzamelingenleer en functionaalanalyse . Hij bestudeerde in het bijzonder partieel geordende verzamelingen en de naar hem vernoemde Hausdorffruimten . Hij publiceerde zijn filosofische en literaire werken onder het pseudoniem Paul Mongr©. Hausdorff studeerde in Leipzig en was daar docent wiskunde tot 1910, waarna hij professor in de wiskunde werd in Bonn . Hoewel de nazi 's aan de macht kwamen en Hausdorff joods was, werd hij als ge«erbiedigde universitaire professor niet vervolgd. Zijn abstracte wiskunde werd echter wel aan de kaak gesteld en hij verloor zijn positie in 1935. Toen hij in 1942 niet meer kon voorkomen dat hij naar een concentratiekamp zou worden afgevoerd, pleegde Hausdorff samen met zijn vrouw en schoonzuster

He also developed Hausdorff spaces In addition to his work in set theory Hausdorff developed the concepts of metric and topological spaces Hausdorff sought to develop the idea of "closeness" without any dependency on being able to "measure" the distance between these points. As a result of the Nazi Nuremberg Laws of 1935, Hausdorff was forced to leave his academic position at Bonn and, although he remained mathematically active for several more years, his research could only be published outside Germany. In January 1942, when internment in a concentration camp became imminent, Hausdorff, his wife, and her sister committed suicide together (Burton 1995).

Return to The Worlds of David Darling INDEX LATEST NEWS ARCHIVE ... Z entire Web this site Hausdorff, Felix (1868-1942) A German mathematician who is considered to be one of the founders of modern topology and who also did significant work in set theory and functional analysis. Among several concepts named after him is the Hausdorff dimension , which gives a way of assigning a fractional dimension to a curve or shape. Hausdorff also published philosophical and literary works under the pseudonym "Paul Mongré." He studied at Leipzig and taught mathematics there until 1910, when he became professor of mathematics at Bonn. When the Nazis came to power, Hausdorff, a Jew, felt that as a respected university professor he would be safe from persecution. However, his abstract mathematics was denounced as useless and "un-German" and he lost his position in 1935. He sent his daughter to Britain but stayed with his wife in Germany. When in 1942 he could no longer avoid being sent to a concentration camp, he committed suicide together with his wife and sister-in-law. BACK TO TOP var site="s13space1234"

Return to The Worlds of David Darling INDEX LATEST NEWS ARCHIVE ... Z entire Web this site Hausdorff dimension A way to accurately measure the dimension of complicated sets such as fractals . The Hausdorff dimension, named after Felix Hausdorff , coincides with the more familiar notion of dimension in the case of well-behaved sets. For example a straight line or an ordinary curve, such as a circle, has a Hausdorff dimension of 1; any countable set has a Hausdorff dimension of 0; and an n -dimensional Euclidean space has a Hausdorff dimension of n . But a Hausdorff dimension is not always a natural number . Think about a line that twists in such a complicated way that it starts to fill up the plane. Its Hausdorff dimension increases beyond 1 and takes on values that get closer and closer to 2. The same idea of ascribing a fractional dimension applies to a plane that contorts more and more in the third dimension: its Hausdorff dimension gets closer and closer to 3. As a specific example, the fractal known as the Sierpinski carpet has a Hausdorff dimension of just over 1.89.

Felix was born into a wealthy family and this had quite an influence on his life and career since he never had the problem of having to work to support himself financially. Felix was stll a young boy when the family moved from Breslau to Leipzig, and it was in Leipzig that he grew up. At school he had wide interests and, in addition to mathematics, he was attracted to literature and music. In fact he wanted to pursue a career in music as a composer but his parents put pressure on him to give up the idea of becoming a composer. They achieved this, but only after quite an effort for Felix had his heart set on the idea, and after this he turned towards mathematics as the subject to study at university. Hausdorff studied at Leipzig University under Heinrich Bruns and Adolph Mayer , graduating in 1891 with a doctorate in applications of mathematics to astronomy. His thesis was titled

Hausdorff, Felix German mathematician and philosopher who developed the branch of mathematics known as topology, in which he formulated the theory of point sets. He investigated general closure spaces, and formulated Hausdorff's maximal principle in general set theory. Hausdorff was born in Breslau, Germany (now Wroclaw, Poland), and studied at Berlin, Freiburg, and Leipzig. In 1902 he was appointed professor at Leipzig, later moving to Bonn. During World War II he committed suicide rather than be sent to a concentration camp. Hausdorff formulated a theory of topological and metric spaces, proposing that such spaces be regarded as sets of points and sets of relations among the points, and introduced the principle of duality. This principle states that an equation between sets remains valid if the sets are replaced by their complements and the symbol for union is exchanged for that of intersection. He also created what are now called Hausdorff's neighbourhood axioms; from these four axioms he derived Hausdorff's topological spaces. A topological space is understood to be a set E of elements x and certain subsets Sx of E which are known as neighbourhoods of x.

It was introduced in by the mathematician Felix Hausdorff . Many of the technical developments used to compute the Hausdorff dimension for highly irregular sets were obtained by Abram Samoilovitch Besicovitch . For this reason, Hausdorff dimension is sometimes referred to as Hausdorff-Besicovitch dimension . It is also less frequently called the capacity dimension or fractal dimension Intuitively, the dimension of a set (for example, a subset of Euclidean space ) is the number of independent parameters needed to describe a point in the set. One mathematical concept which closely models this na¯ve idea is that of topological dimension of a set. For example a point in the plane is described by two independent parameters (the
