The department is saddened by the death of Tsuneo Tamagawa, Andrew W. Phillips Professor Emeritus of Mathematics on December 30, 2017 at the age of 92. Tamagawa was widely known in the mathematics field for his fundamental contributions to research on the arithmetic aspects of classical groups, which involve mathematical theories having their roots in geometry. Perhaps his most celebrated achievement was his synthesis of the so-called “Tamagawa Number,” which opened new areas of thought in a field that had been worked over heavily by number theorists for generations. His articles on mathematical theory were published in journals in both Japan and the United States.
