With best regards, Betül Tanbay President of the Turkish Mathematical Society Report on the state of mathematics in Turkey (2005-2015) This is an overview of the status of Mathematics in Turkey, prepared for the IMU for promotion from Group I to Group II by the adhering organization, the Turkish Mathematical Society (TMD). 1-HISTORICAL BACKGROUND 2-SOCIETIES AND CENTERS RELATED TO MATHEMATICAL SCIENCES 3-NUMBER OF PUBLICATIONS BY SUBJECT CATEGORIES 4-NATIONAL CONFERENCES AND WORKSHOPS HELD IN TURKEY BETWEEN 2013-2015 5-INTERNATIONAL CONFERENCES AND WORKSHOPS HELD IN TURKEY BETWEEN 2013-2015 6-NUMBERS OF STUDENTS AND TEACHING STAFF IN MATHEMATICAL SCIENCES IN TURKEY FOR THE 2013-2014 ACADEMIC YEAR AND THE 2014-2015 ACADEMIC YEAR 7- RANKING AND DOCUMENTS OF TURKEY IN MATHEMATICAL SCIENCES 8- PERIODICALS AND PUBLICATIONS 1-HISTORICAL BACKGROUND Two universities, the Istanbul University and the Istanbul Technical University have been influential in creating a mathematical community in Turkey. The Royal School of Naval Engineering, "Muhendishane-i Bahr-i Humayun", was established in 1773 with the responsibility to educate chart masters and ship builders. Gaining university status in 1928, the Engineering Academy continued to provide education in the fields of engineering and architecture and, in 1946, Istanbul Technical University became an autonomous university which included the Faculties of Architecture, Civil Engineering, Mechanical Engineering, and Electrical and Electronic Engineering. -
Mathematisches Forschungsinstitut Oberwolfach the Arithmetic of Fields
Mathematisches Forschungsinstitut Oberwolfach Report No. 05/2009 The Arithmetic of Fields Organised by Moshe Jarden (Tel Aviv) Florian Pop (Philadelphia) Leila Schneps (Paris) February 1st – February 7th, 2009 Abstract. The workshop “The Arithmetic of Fields” focused on a series of problems concerning the interplay between number theory, arithmetic and al- gebraic geometry, Galois theory, and model theory, such as: the Galois theory of function fields / covers of varieties, rational points on varieties, Galois co- homology, local-global principles, lifting/specializing covers of curves, model theory of finitely generated fields, etc. Mathematics Subject Classification (2000): 12E30. Introduction by the Organisers The sixth conference on “The Arithmetic of Fields” was organized by Moshe Jar- den (Tel Aviv), Florian Pop (Philadelphia), and Leila Schneps (Paris), and was held in the week February 1–7, 2009. The participants came from 14 countries: Germany (14), USA (11), France (7), Israel (7), Canada (2), England (2), Austria (1), Brazil (1), Hungary (1), Italy (1), Japan (1), South Africa (1), Switzerland (1), and The Netherlands (1). All together, 51 people attended the conference; among the participants there were thirteen young researchers, and eight women. Most of the talks concentrated on the main theme of Field Arithmetic, namely Galois theory and its interplay with the arithmetic of the fields. Several talks had an arithmetical geometry flavour. All together, the organizers find the blend of young and experienced researchers and the variety of subjects covered very satisfactory.

Cahit Arf: Exploring His Scientific Influence Using Social Network Analysis and Author Co-Citation Maps
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. -

Abraham Robinson, 1918 - 1974
BULLETIN OF THE AMERICAN MATHEMATICAL SOCIETY Volume 83, Number 4, July 1977 ABRAHAM ROBINSON, 1918 - 1974 BY ANGUS J. MACINTYRE 1. Abraham Robinson died in New Haven on April 11, 1974, some six months after the diagnosis of an incurable cancer of the pancreas. In the fall of 1973 he was vigorously and enthusiastically involved at Yale in joint work with Peter Roquette on a new model-theoretic approach to diophantine problems. He finished a draft of this in November, shortly before he underwent surgery. He spoke of his satisfaction in having finished this work, and he bore with unforgettable dignity the loss of his strength and the fading of his bright plans. He was supported until the end by Reneé Robinson, who had shared with him since 1944 a life given to science and art. There is common consent that Robinson was one of the greatest of mathematical logicians, and Gödel has stressed that Robinson more than any other brought logic closer to mathematics as traditionally understood. His early work on metamathematics of algebra undoubtedly guided Ax and Kochen to the solution of the Artin Conjecture. One can reasonably hope that his memory will be further honored by future applications of his penetrating ideas. Robinson was a gentleman, unfailingly courteous, with inexhaustible enthu siasm. He took modest pleasure in his many honors. He was much respected for his willingness to listen, and for the sincerity of his advice. As far as I know, nothing in mathematics was alien to him. Certainly his work in logic reveals an amazing store of general mathematical knowledge. -

Doing Mathematics in Emmy Noether's Time
Doing mathematics in Emmy Noether’s time: A survey on the study and work situation of women mathematicians in Germany between the two World Wars Prof.Dr.habil. Ilka Agricola Philipps-Universit¨at Marburg Madrid, April 2019 — a tribute to the 100th anniversary of Noether’s habilitation — 1 What this talk is about. • History of science, because science is done by scientists, so their working and living conditions influence scientific progress • To be seen in historical context: Industrialisation and wars lead to deep changes in society, the formation of a working class, the need for engineers and other professionals, and sometimes a shortage of male employees • Partially based on a case study carried out in Marburg (2017/18) about the first generation of female math students in Marburg (see refs.) • Applies mainly to Germany and, to some extent, neighbouring countries; very different from situation in South Europe and elsewhere 1 Marburg: An old traditional university • Founded in 1527 by Philip I, Landgrave of Hesse • oldest protestant university in the world • Of relevance for us: As a consequence of the Austro-Prussian War (1866), Marburg and G¨ottingen became part of Prussia (the Electorate of Hesse and and the Kingdom of Hannover disappeared) • Hence, Marburg is typical for the development of universities in Germany’s largest state – to be honest, they developed much better after 1866. 1 Das ‘Mathematische Seminar’ • Mathematics was taught in Marburg since the foundation of the university 1527 (Papin, Wolff. ) • 1817: Foundation of the ‘Mathematisch- physikalisches Institut’ by Christian Gerling (student of C.F. Gauß) • 1885: Foudation of the Faculty by H. -
Witt's Cancellation Theorem Seen As a Cancellation 1
WITT'S CANCELLATION THEOREM SEEN AS A CANCELLATION SUNIL K. CHEBOLU, DAN MCQUILLAN, AND JAN´ MINA´ Cˇ Dedicated to the late Professor Amit Roy Abstract. Happy birthday to the Witt ring! The year 2017 marks the 80th anniversary of Witt's famous paper containing some key results, including the Witt cancellation theorem, which form the foundation for the algebraic theory of quadratic forms. We pay homage to this paper by presenting a transparent, algebraic proof of the Witt cancellation theorem, which itself is based on a cancellation. We also present an overview of some recent spectacular work which is still building on Witt's original creation of the algebraic theory of quadratic forms. 1. Introduction The algebraic theory of quadratic forms will soon celebrate its 80th birthday. Indeed, it was 1937 when Witt's pioneering paper [24] { a mere 14 pages { first introduced many beautiful results that we love so much today. These results form the foundation for the algebraic theory of quadratic forms. In particular they describe the construction of the Witt ring itself. Thus the cute little baby, \The algebraic theory of quadratic forms" was healthy and screaming with joy, making his father Ernst Witt very proud. Grandma Emmy Noether, Figure 1. Shortly after the birth of the Algebraic Theory of Quadratic Forms. had she still been alive, would have been so delighted to see this little tyke! 1 Almost right 1Emmy Noether's male Ph.D students, including Ernst Witt, were often referred to as \Noether's boys." The reader is encouraged to consult [6] to read more about her profound influence on the development of mathematics. -

DAUBEN Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoirs, VOLUME 82 PUBLISHED 2003 BY THE NATIONAL ACADEMY PRESS WASHINGTON, D.C. Courtesy of Yale University News Bureau ABRAHAM ROBINSON October 6, 1918–April 11, 1974 BY JOSEPH W. DAUBEN Playfulness is an important element in the makeup of a good mathematician. —Abraham Robinson BRAHAM ROBINSON WAS BORN on October 6, 1918, in the A Prussian mining town of Waldenburg (now Walbrzych), Poland.1 His father, Abraham Robinsohn (1878-1918), af- ter a traditional Jewish Talmudic education as a boy went on to study philosophy and literature in Switzerland, where he earned his Ph.D. from the University of Bern in 1909. Following an early career as a journalist and with growing Zionist sympathies, Robinsohn accepted a position in 1912 as secretary to David Wolfson, former president and a lead- ing figure of the World Zionist Organization. When Wolfson died in 1915, Robinsohn became responsible for both the Herzl and Wolfson archives. He also had become increas- ingly involved with the affairs of the Jewish National Fund. In 1916 he married Hedwig Charlotte (Lotte) Bähr (1888- 1949), daughter of a Jewish teacher and herself a teacher. 1Born Abraham Robinsohn, he later changed the spelling of his name to Robinson shortly after his arrival in London at the beginning of World War II. This spelling of his name is used throughout to distinguish Abby Robinson the mathematician from his father of the same name, the senior Robinsohn. -
