Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU)

The University of Tokyo Graduate School of Mathematical Sciences Professor and Kavli IPMU Principal Investigator Toshiyuki Kobayashi has been selected to join the 2017 class of the Fellows of the American Mathematical Society (AMS).

The Fellows of the American Mathematical Society program recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics.

The responsibilities of Fellows are to take part in the election of new Fellows, to present a “public face” of excellence in mathematics, and to advise the President and the Council on public matters when requested. A list of Fellows is published on the AMS website.

Via his research on "theory of discontinuous groups", "branching laws of infinite-dimensional representations", and "global analysis on minimal representations", Kobayashi has paved the way for a new theory of global analysis via symmetries, and pioneered revolutionary breakthroughs in mathematics. In awarding him the fellowship, the AMS analyzed Kobayashi’s contribution to Structure Theory and Representation Theory of Reduction Lie Groups.

Upon becoming a Fellow, Kobayashi said: “I am honored and delighted to be selected to join the Fellows of the American Mathematical Society. I will work hard to live up to the expectation and to contribute to progress in mathematics.”

In addition, Kavli IPMU Director Hitoshi Murayama, said: “It always strikes me that Toshiyuki is fearless in attacking the most difficult problems in mathematics. In addition, he combines his prowess in all areas of mathematics, ranging from algebra, geometry, to analysis, a rare gift. I heartily congratulate him for this honor which he clearly deserves.”

The new Fellows will be formally inducted at the upcoming Joint Mathematics Meetings of the American Mathematical Society, to be held in Atlanta in January 2017.
