How this was complished is shown with three examples of careers of famous mathematicians. 1 Introduction This symposium is dedicated to the development of mathematics in the Austro- Hungarian monarchy in the time from 1850 to 1914. At the beginning of this period, in the middle of the 19th century the level of teaching and researching mathematics was very low – with a few exceptions – due to the influence of the jesuits in former centuries, and due to the reclusive period in the first half of the 19th century. But even in this time many efforts were taken to establish a higher education. -

uniform Uniform Distribution Theory 5 (2010), no.1, 1–12 distribution theory EDMUND HLAWKA (1916 - 2009) The eminent Austrian mathematician Edmund Hlawka passed away on Feb- ruary 19, 2009. He was born in 1916 in Bruck an der Mur (Styria) and obtained his complete education in Vienna. Edmund Hlawka was a student at the mathe- matics department of the university of Vienna in the thirties of the last century. This department was very famous in the period 1918 – 1938: Hahn, Wirtinger, Furtw¨angler, G¨odel, Menger and many other mathematicians worked there. Edmund Hlawka wrote his first papers as a student, and they were devoted to the asymptotic analysis of special functions, see [Top 151 in the enclosed list of publications which was taken from Mathematical Reviews]. He received his PhD in 1938 (supervisor: N. Hofreiter) with a remarkable result on the diophantine approximation of complex linear forms, see [Top 149]. Edmund Hlawka became famous all over the world after the publication of his habilitation thesis (see Top 146), where he solved an old problem of Minkowski in the geometry of numbers. After the war he became a full professor of mathematics at the University of Vienna where he remained until 1981. Then he moved to Vienna University of Technology. This position he held until his retirement in 1987. There are several results which are connected with the name of Edmund Hlawka, and for which he is widely known: i) The Hornich-Hlawka inequality in Euclidean vector spaces: ∣∣a∣∣ + ∣∣b∣∣ + ∣∣c∣∣ + ∣∣a + b + c∣∣ ≥ ∣∣a∣∣ + ∣∣b∣∣ + ∣∣c∣∣ + ∣∣b + c∣∣ The original proof is due to H. -

This document has been digitized, optimized for electronic delivery and stamped with digital signature within the project DML-CZ: The Czech Digital Mathematics Library http://dml.cz THE RECEPTION OF BOLYAI’S GEOMETRY IN THE AUSTRO-HUNGARIAN EMPIRE KATI MUNKACSY Abstract: There is plenty of detailed literature on the history of non-Euclidean geometry. I would like to mention some important mathematicians such as Euclid, Playfair, Saccheri, Lambert, Bolyai, Lobachevsky, Gauß, Riemann, Klein, Halsted, Beltrami, and Hilbert who were interested in the fundaments of geometry. We know less about the reception of Farkas Bolyai’s work in Hungary’s neighbor countries, in the Austrian-Hungarian Empire. With the help of my colleagues I collected some data on publications and university lectures on the reception of hyperbolic geometry in Vienna, Prague, Beograd and Kolozsvár. 1 Introduction 1.1 The birth of Non-Euclidean geometry Janos Bolyai introduced non-Euclidean geometry, or “new geometry” as he called it, in an appendix of the book “Tentamen ...” by his father Farkas Bolyai. -

Vorwort Heft 4-09 Hans-Christoph Grunau Was macht mathematisches Arbeiten aus?“, fragen Kristina Reiss und Stefan Ufer. ” Die M ¨oglichkeit, Erkenntnisse durch Beweisen zu gewinnen, ist ein Alleinstellungsmerk- mal der Mathematik. Die Autoren definieren zun ¨achst sorgf ¨altig ihre zentralen Begriffe Argumentieren, Begr unden,¨ Beweisen“ und reflektieren deren Rolle in den Bildungsstan- ” dards und beim Lehren und Lernen in Schule und Hochschule. Der Schwerpunkt dieses Ubersichtsartikels¨ liegt auf empirischen Untersuchungen, inwieweit verschiedene Formen von Wissen und Probleml ¨osungsstrategien die F ¨ahigkeit zum Argumentieren, Begr unden,¨ Beweisen beeinflussen. Der Beitrag von Kristina Reiss und Stefan Ufer l ¨adt ein, die ei- gene und auch die allgemein gepflegte Unterrichtspraxis mit dem Ziel zu uberdenken,¨ dass Sch ulerinnen¨ und Sch uler,¨ Studentinnen und Studenten mehr Freude am und mehr Kompetenz beim Argumentieren, Begr unden¨ und Beweisen entwickeln. Knoten im R3 sind ganz anschauliche Objekte, die Berechnung von Knoteninvarian- ten wie etwa deren Geschlecht oder Gefasertheit jedoch Gegenstand aktueller topologi- scher Forschung. Der Ubersichtsartikel¨ Knot invariants: Low dimensional topology and ” combinatorics“ von Andr´asI. Stipsicz f uhrt¨ zun ¨achst in einige Grundbegriffe der Kno- tentheorie ein, um dann mit dem Alexander-Polynom eine klassische und der Knoten- Floer-Homologie eine erst wenige Jahre alte Knoteninvariante vorzustellen. Ganz aktuell ist das Ergebnis, dass die Knoten-Floer-Homologie rein kombinatorisch behandelt werden kann. Damit wird – zumindest grunds ¨atzlich – eine rein algorithmische Bestimmung die- ser Knoteninvariante und damit z.B. auch des Knotengeschlechts oder der Gefasertheit erm ¨oglicht. Am 19. Februar dieses Jahres verstarb mit Edmund Hlawka einer der bedeutendsten ¨osterreichischen Mathematiker des 20.

Scientific Report for 2003
The Erwin Schr¨odinger International Boltzmanngasse 9/2 ESI Institute for Mathematical Physics A-1090 Vienna, Austria Scientific Report for 2003 Impressum: Eigent¨umer, Verleger, Herausgeber: The Erwin Schr¨odinger International Institute for Math- ematical Physics, Boltzmanngasse 9, A-1090 Vienna. Redaktion: Joachim Schwermer, Jakob Yngvason Supported by the Austrian Federal Ministry for Education, Science and Culture. A PREFACE BY THE PRESIDENT 1 A preface by the President The Erwin Schr¨odinger International Institute for Mathematical Physics (ESI) was officially opened in April 1983 and is now in its 11th year of operation. Within these eleven years the ESI has established itself as a research centre of international excellence in the mathematical sciences. To date well over 2400 scientists have visited the Institute, many of them repeatedly, and most of the leading researchers in mathematics and mathematical physics have worked here at some stage during this period. The research activities of the ESI are documented in almost 1500 ESI preprints, the overwhelming majority of which were subsequently published in leading international journals. Far from having been a routine year for the Institute, 2003 saw some important developments and changes at the ESI. The first and most alarming of these was a significant cut in the basic funding of ESI (and of practically all comparable Austrian research institutions) by the Ministry of Science: in June 2003 we were notified of a 14.3% reduction in our recurrent grant for 2003. Since our recurring costs are fairly constant, this meant an effective reduction of our scientific budget by well over 25%. Although this forced us to take quite harsh emergency measures we were able to maintain all our scientific activities, albeit at a somewhat reduced level, by using reserves.
