Tsuneo Tamagawa
Tsuneo Tamagawa (Japanese: 玉河 恒夫, ''Tamagawa Tsuneo'', 11 December 1925 in Tokyo – 30 December 2017 in New Haven, Connecticut) was a mathematician. He worked on the arithmetic of classical groups. Tamagawa received his PhD in 1954 at the University of Tokyo under Shōkichi Iyanaga. Tamagawa was a visiting scholar at the Institute for Advanced Study in 1955/6, 1958, and 1970. He has been on the Yale University faculty since 1963, and became emeritus in 1996. He introduced the Tamagawa numbers, which are measures for algebraic groups over algebraic number fields. These measures play an essential role in conjectures on arithmetic algebraic geometry, such as those of Spencer Bloch and Kazuya Kato. Tamagawa's doctoral students included Doris Schattschneider and Audrey Terras.

Japanese Language
is the principal language of the Japonic languages, Japonic language family spoken by the Japanese people. It has around 123 million speakers, primarily in Japan, the only country where it is the national language, and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language. There have been many Classification of the Japonic languages, attempts to group the Japonic languages with other families such as Ainu languages, Ainu, Austronesian languages, Austronesian, Koreanic languages, Koreanic, and the now discredited Altaic languages, Altaic, but none of these proposals have gained any widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yale University Faculty
Yale University is a Private university, private Ivy League research university in New Haven, Connecticut, United States. Founded in 1701, Yale is the List of Colonial Colleges, third-oldest institution of higher education in the United States, and one of the nine colonial colleges chartered before the American Revolution. Yale was established as the Collegiate School in 1701 by Congregationalism in the United States, Congregationalist clergy of the Connecticut Colony. Originally restricted to instructing ministers in theology and sacred languages, the school's curriculum expanded, incorporating humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first Doctor of Philosophy, PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew rapidly after 1890 due to the expansion of the physical campus and its scientif ...

University Of Tokyo Alumni
A university () is an educational institution, institution of tertiary education and research which awards academic degrees in several Discipline (academia), academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. The first universities in Europe were established by Catholic Church, Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2 ...

Audrey Terras
Audrey Anne Terras (born September 10, 1942) is an American mathematician who works primarily in number theory. Her research has focused on quantum chaos and on various types of zeta functions. Early life and education Audrey Terras was born September 10, 1942, in Washington, D.C. She received a BS degree in mathematics from the University of Maryland, College Park (UMD) in 1964, and MA and PhD degrees from Yale University in 1966 and 1970 respectively. She was married to fellow UMD alumnus Riho Terras. She stated in a 2008 interview that she chose to study mathematics because "The U.S. government paid me! And not much! It was the time of Sputnik, so we needed to produce more mathematicians, and when I was deciding between Math and History, they weren’t paying me to do history, they were paying me to do math." Career Terras joined the University of California, San Diego, as an assistant professor in 1972, and became a full professor there in 1983. She retired in 2010, an ...

Spencer Bloch
Spencer Janney Bloch (born May 22, 1944; New York City) is an American mathematician known for his contributions to algebraic geometry and algebraic ''K''-theory. Bloch is a R. M.
