Mustafa Kemal Atatürk and denomination 10.


10 Lira 2009

Mustafa Kemal Atatürk (19 May 1881 - 10 November 1938) was a Turkish army officer, reformist statesman, and the first President of Turkey. He is credited with being the founder of the Republic of Turkey. His surname, Atatürk (meaning "Father of the Turks"), was granted to him in 1934 and forbidden to any other person by the Turkish parliament.

Atatürk was a military officer during World War I. Following the defeat of the Ottoman Empire in World War I, he led the Turkish National Movement in the Turkish War of Independence. Having established a provisional government in Ankara, he defeated the forces sent by the Allies. His military campaigns led to victory in the Turkish War of Independence. Atatürk then embarked upon a program of political, economic, and cultural reforms, seeking to transform the former Ottoman Empire into a modern and secular nation-state. Under his leadership, thousands of new schools were built, primary education was made free and compulsory, and women were given equal civil and political rights, while the burden of taxation on peasants was reduced. The principles of Atatürk's reforms, upon which modern Turkey was established, are referred to as Kemalism.

Cahit Arf

The engraving on banknote is made after this photo of Cahit Arf.

Cahit Arf (11 October 1910 - 26 December 1997) was a Turkish mathematician. He is known for the Arf invariant of a quadratic form in characteristic 2 (applied in knot theory and surgery theory) in topology, the Hasse-Arf theorem in ramification theory, Arf semigroups, and Arf rings.

Cahit Arf was born on 11 October 1910 in Selanik (Thessaloniki), which was then a part of the Ottoman Empire. His family migrated to Istanbul with the outbreak of the Balkan War in 1912. The family finally settled in İzmir where Cahit Arf received his primary education. Upon receiving a scholarship from the Turkish Ministry of Education he continued his education in Paris and graduated from École Normale Supérieure.

Returning to Turkey, he taught mathematics at Galatasaray High School. In 1933 he joined the Mathematics Department of Istanbul University. In 1937 he went to Göttingen, where he received his PhD from the University of Göttingen and he worked with Helmut Hasse and Josue Cruz de Munoz. He returned to Istanbul University and worked there until his involvement with the foundation work of Scientific and Technological Research Council (TÜBİTAK) upon President Cemal Gursel's appointment in 1962. After serving as the founding director of the council in 1963, he joined the Mathematics Department of Robert College in Istanbul. Arf spent the period of 1964-1966 working at the Institute for Advanced Study in Princeton, New Jersey. He later visited University of California, Berkeley for one year.

Upon his final return to Turkey, he joined the Mathematics Department of the Middle East Technical University and continued his studies there until his retirement in 1980. Arf received numerous awards for his contributions to mathematics, among them are: İnönü Award in 1948, Scientific and Technological Research Council of Turkey (TÜBİTAK) Science Award in 1974, and Commandeur des Palmes Academiques (France) in 1994. Arf was a member of the Mainz Academy and the Turkish Academy of Sciences. He was the president of the Turkish Mathematical Society from 1985 until 1989. Arf died on December 26, 1997 in Bebek, Istanbul, at the age of 87. His collected works were published, in 1988, by the Turkish Mathematical Society.

Arf's influence on Science in general and Mathematics in particular was profound. Although he had very few formal students, many of the mathematicians of Turkey, at some time of their careers, had fruitful discussions on their field of interest with him and had received support and encouragement.

He facilitated the now-celebrated visit of Robert Langlands to Turkey (now famous for the Langlands program, among many other things); during which Langlands worked out some arduous calculations on the epsilon factors of Artin L-functions.

Arf semigroups. Centered is Hasse-Arf theorem (Arf invariant), arithmetic series, abacus, binary.

In mathematics, the Arf invariant of a nonsingular quadratic form over a field of characteristic 2 was defined by Turkish mathematician Cahit Arf (1941), when he started the systematic study of quadratic forms over arbitrary fields of characteristic 2.

Denominations in numerals are in three corners, in words lower, centered.


Interesting fact: On larger denominations Mustafa Kemal Ataturk is looking exactly at you. The angle of his bust is turning more from you on smaller denominations. That's why Turks saying: "If you have just little money, then Ataturk will not even look at you".
