He is widely known for his Incompleteness Theorems, which are among the handful of landmark theorems in twentieth century mathematics, but his work touched every field of mathematical logic, if it was not in most cases their original stimulus. In his philosophical work Gödel formulated and defended mathematical Platonism, the view that mathematics is a descriptive science, or alternatively the view that the concept of mathematical truth is objective. On the basis of that viewpoint he laid the foundation for the program of conceptual analysis within set theory.

He is recognized as the founder of the Romanian school of differential geometry. Țițeica wrote about 400 articles, of which 96 are scientific projects, most addressing problems of differential geometry. Țițeica discovered a new category of surfaces and a new category of curves which now carry his name. His contributions represent the beginning of a new chapter in mathematics, namely the affine differential geometry. He also studied webs in n-dimensional space, defined through Laplace equations.

He is known for his influential arguments for substance dualism, where mind and body are considered to have distinct essences, one being characterized by thought, the other by spatial extension. He has been dubbed the "Father of Modern Philosophy" and the "Father of Modern Mathematics." He is also known as Cartesius. Descartes first proposed that each point in two dimensions can be described by two numbers on a plane, one giving the point’s horizontal location and the other the vertical location, which have come to be known as Cartesian coordinates.

In the early seventies, he developed alternative set theory (alternative to the classical Cantor theory), which he subsequently developed in a series of articles and monographs. Vopěnka’s name is associated with many mathematical achievements, including Vopěnka's principle. Since the mid-eighties he concerned himself with philosophical questions of mathematics (particularly vis-à-vis Husserlian phenomenology). Vopěnka served as the Minister of Education of the Czech Republic (then part of Czechoslovakia) from 1990 to 1992.

He was a member of the Lviv School of Mathematics. In the 1930’s he went to the United States and had a very successful career there. He joined the Manhattan Project which was the US's wartime effort to create the atomic bomb. Stanisław Ulam and Edward Teller came up with the Teller–Ulam design, which is the basis for all thermonuclear weapons. Ulam believed that nuclear weapon would deter humans from creating military conflicts. He also discovered the concept of the cellular automaton, invented the Monte Carlo method of computation, and suggested nuclear pulse propulsion.

    Cahit Arf: Exploring His Scientific Influence Using Social Network Analysis and Author Co-citation Maps 1 2 Yaşar Tonta and A. Esra Özkan Çelik 1 [email protected] Department of Information Management, Hacettepe University, 06800 Beytepe, Ankara, TR 2 [email protected] Registrar's Office, Hacettepe University, 06800 Beytepe, Ankara, TR Abstract Cahit Arf (1910-1997), a famous Turkish scientist whose picture is depicted in one of the Turkish banknotes, is a well known figure in mathematics with his discoveries named after him (e.g., Arf invariant, Arf rings, the Hasse- Arf theorem). Although Arf may not be considered as a prolific scientist in terms of number of papers (he authored a total of 23 papers), his influence on mathematics and related disciplines was profound. As he was active before, during and after the World War II, Arf’s contributions were not properly listed in citation indexes and thus did not generate that many citations even though several papers with “Arf” in their titles appeared in the literature. This paper traces the influence of Arf in scientific world using citation analysis techniques first. It reviews the scientific impact of Arf by analyzing both the papers authored by Arf and papers whose titles or keywords contain various combinations of “Arf rings”, “Arf invariant”, and so on. The paper then goes on to study Arf’s contributions using social network analysis and author co-citation analysis techniques. CiteSpace and pennant diagrams are used to explore the scientific impact of Arf by mapping his cited references derived from Thomson Reuters’ Web of Science (WoS) database.

  • Introduction of Langlands
    Peter Roquette 4. Nov. 2004 Mathematisches Institut, Universit¨at Heidelberg Introduction of Langlands at the Arf lecture, 11 November 2004.1 Ladies and Gentlemen ! It is my pleasure and a great honor to me to introduce Robert Langlands as the speaker of the Arf Lecture of this year 2004, here at the Middle East Technical University. Professor Langlands is a permanent member of the Institute for Advanced Study in Princeton, which is one of the most pres- tigious places for mathematical research studies. He has received a number of highly valued awards, among them the Cole Prize in Number Theory from the American Mathematical Society in 1982, the National Academy of Sciences reward in Mathema- tics in 1988, and the Wolf prize from the Wolf foundation in Israel 1996. He is elected fellow of the Royal Society of Canada and the Royal Society of London, and he has received honorary doctorates from at least 7 universities (to my knowledge). In the laudation for the Wolf prize it was said that he received the prize for his “ path-blazing work and extraordinary insights in the fields of number theory, automorphic forms and group representations”. 1Each year there is scheduled a special colloquium lecture at the Middle East Technical University in Ankara, commemorating Cahit Arf who had served as a professor for many years at METU. In the year 2004 the invited speaker was Robert Langlands, and I had been asked to chair his lecture. The following text was read to introduce the speaker. P.Rq. Introduction of Langlands 4.11.04 Seite 2 Ladies and gentlemen, while I was preparing the text for this introduction it soon became clear to me that in this short time I would not be able to describe, not even approximately, Lang- lands’ rich work, its underlying ideas, its enormous impact on the present mathematical research world wide, and its consequence for the future picture of Mathematics.

  • A Short Survey on Mathematical Work of Cemal Ko¸C
    Turk J Math 34 (2010) , 433 – 440. c TUB¨ ITAK˙ doi:10.3906/mat-1009-43 A short survey on mathematical work of Cemal Ko¸c Ismail˙ S¸. G¨ulo˘glu IfirstmetCemalKo¸c during Spring semester of 1977. He was then a young associate professor at the Middle East Technical University, Ankara, and I was a Ph.D. student attending his graduate course on noncommutative rings. I had previously attended lectures in Germany given by leading experts on several topics in algebra, yet the course I took that year from Cemal Ko¸c was the one that has left a strong impression on me as a live example of how one should lecture and teach. Later, on many other occasions, I had the chance to observe his enthusiasm for and dedication to teaching. Being a first grade researcher as well, he possessed a combination of talents that one does not find very often. Unfortunately, I won’t be able to give you a taste of what his teaching was like but instead I shall try to summarize his mathematical research. Cemal Ko¸c was born in Kırcaali, Bulgaria, in 1943. After a short while, he and his family had to immigrate to Turkey. His family struggled through many economic problems and they had to move a lot, which affected his education as well. It started in Samsun, then continued in Tokat for a while, and ended in 1963 with his graduation from the department of mathematics and astronomy of Ankara University. After graduation he began work as a math teacher in a high school.

Later I had given a talk with the same title on October 5, 2009 at the conference on Positivity, Valuations, and Quadratic Forms in Konstanz. In the discussion after the talk I learned that there may be an error in Arf's paper and perhaps his main theorem has to be modified. I am in- debted to Karim Johannes Becher for this comment. Indeed, after another check I found the error in the proof of one of Arf's lemmas.
