Extractions: Home Best Texans Volunteer ... Volunteer Does there exist a subset of the plane such that every straight line intersects the set at exactly two points? Remark. A set that intersects every line of the plane in exactly n points is called an n-set . A 1-set is clearly impossible; this question asks whether 2-sets exist.) The answer is Yes, although it's hard to visualize such a set. This result was proved by Stefan Mazurkiewicz in 1914, and we will show his proof. In this article we will show how to construct the set using transfinite recursion. Surprisingly the construction uses almost no facts about geometry or the plane, but it does use some facts about transfinite numbers, so you should be familiar with those. (Most books on set theory discuss this topic.) Let's practice on a simpler version of the problem before we take a leap into the transfinite. Suppose we are given a finite collection of straight lines in the plane, L , ..., L

Sierpinski Carpet So the Sierpinski carpet was actually invented by stefan mazurkiewicz, who in1913 wrote his Ph.D. thesis under the supervision of Sierpinski on curves http://ecademy.agnesscott.edu/~lriddle/ifs/carpet/carpet.htm

Divide this into 9 smaller congruent squares. Remove the interior of the center square (that is, do not remove the boundary) to get C(1) . Now subdivide each of the eight remaining solid squares into 9 congruent squares and remove the center square from each to obtain C(2) .

Extractions: Died: August 31, 1945, in Lwow (Lemberg, Lviv), Soviet Union (now Ukraine) Accomplishments: Founded the important modern mathematical field of functional analysis and made major contributions to the theory of topological vector spaces. In addition, he contributed to measure theory, integration, the theory of sets and orthogonal series. Stefan Banach He was in Kiev when Germany invaded the Soviet Union, but he returned immediately to his family in Lwow. He was arrested, but after few weeks he was released. He also survived the Nazi slaughter of Polish university professors. His advisor Lomnicki was among those who perished. From the end of 1941 through the remainder of the Nazi occupation (July 1944), Banach worked feeding lice in Prof. Weigels Institute in Lwow. After the Soviets reentered Lwow, Banach contacted his Soviet friend Sobolev, who wrote about this encounter: "...and despite the grave illness that was undercutting his strength, Banach's eyes were still lively. He remained the same sociable, cheerful and extraordinarily well-meaning and charming Stefan Banach whom I had seen in Lvov before the war. That is how he remains in my memory: with a great sense of humor, an energetic human being, a beautiful soul and a great talent..." Banach died of lung cancer in Lwow in 1945.

Extractions: Kluwer Academic Publishers, Dordrecht, 1998 The series of Handbooks of the History of General Topology, of which this is the second volume and two more are promised, was originated after a session organized by the American Mathematical Society in San Antonio, Texas, in 1993. The project developed in a four volumes series, of 300-400 pages each, the first one being published in 1997, by the same publisher. General Topology is so vast and has so many different ramifications and interactions with other fields of mathematics that would be very difficult to organize the volumes by clustering subjects or distinct directions. The organizers opted by giving a good space to the comprehensive work of the main proponents of the field that emerged in the beginning of the 20th century. And considerable space is given to sub-areas which developed in the course of the century. The subjects covered are wide-ranging and eclectic. As the previous one, this second volume analyses personalities and specific topics. The geographical spread of the contributors reveal the predominance of Europeans and North Americans in the development of the General Topology. Regrettably, the book does not have a section on the profile of the contributors, such as "About the Contributors", which is common in books of this kind by this publisher. There is a possibility to repair this omission preparing a comprehensive chapter on the contributors in the next volumes. Also, the volume would benefit from an expanded Index. Since page numbering is integrated [this volume begins with page 399], we can expected an overall index in Volume 4.

Extractions: It has named after the Polish mathematician Waclaw Sierpinski (1882-1969), but it was Stefan Mazurkiewicz who found the curve (in 1913). The curve is the only plane locally connected one-dimensional continuum S such that the boundary of each complementary domain of S is a simple closed curve and no two of these complementary domain boundaries intersect. Some kind of shells (conus textilus, conus gloriatnatis) have patterns that resemble the Sierpinksi square. Professor Gerda de Vries of the University of Alberta designed a quilt named ´Sierpinksi Meets Mondrian´ notes 1) Fractal dimension = log N / log e, where N is the number of line segments and e the magnification.

Stefan Krasa and Nicholas C Yannelis Economic Theory , 1994, vol. 4, issue 3, pages 467-71 Abstract: This note provides an elementary short proof of the Knaster-Kuratowski-Mazurkiewicz-Shapley (K-K-M-S) Theorem based on Brouwer's fixed point theorem. The usefulness of the K-K-M-S Theorem lies in the fact that it can be applied to prove directly Scarf's (1967) Theorem, i.e., any balanced game has a non-empty core. We also show that the K-K-M-S Theorem and the Gale-Nikaido-Debreu Theorem can be proved by the same arguments.

Extractions: It seems paradoxical, but is nevertheless true that there are continuous curves which completely fill up higher dimensional spaces such as squares or cubes. The first examples were constructed by Giuseppe Peano (1858-1932) and thus curves of this kind are known as Peano curves . The construction shown above is due to David Hilbert (1862-1943). This space-filling curve which completely fills up the unit square is the limit of a sequence of curves defined iteratively. The first six iterations in this process are shown above. See the following sites for some variants of Hilbert's construction: It was later shown that a wide variety of spaces can be completely filled up by continuous curves. A characterization of all such spaces was given by Hans Hahn (1879-1934) and by Stefan Mazurkiewicz Hahn-Mazurkiewicz Theorem A nonempty Hausdorff topological space can be completely filled up by a continuous curve if and only if the space is compact, connected, locally connected and metrizable.
