Opening Address


Thank you for the introduction. I am Takashi Tsuboi, the Dean of the Graduate School of Mathematical Sciences of the University of Tokyo.

Ladies and Gentlemen, on behalf of the members of our Graduate School, I would like to welcome all of you.
We still feel very sad that Professor Shoshichi Kobayashi passed away last year, but we feel really honored to host this memorial symposium for him.


Professor Shoshichi Kobayashi entered Daiichi Koutougakkou in 1948, but by the reformation of the education system in Japan after the World War II, he entered the University of Tokyo in 1949. He studied in the Department of Mathematics of the Faculty of Science with Kentaro Yano and got the Bachelor degree in 1953. So he is our aluminus member.

After entering the Graduate School, his went to France by the scholarship of the French government. He stayed in Paris and in Strasbourg, and he worked with Ehresmann. Then he went to the University of Washington, Seatle, and became a research assistant of Allendoerfer. He completed his Ph.D. there in 1956 with the dissertation titled "Theory of Connections".

He finally moved to Berkeley in 1962 and he stayed there always as the leader of mathematics especially of geometry as everyone in this auditorium knows. I also learned with the textbook Kobayashi-Nomizu. Many Japanese mathematicians, old and young, visited Berkeley, and every time they were warmly hosted by Professor Shoshichi Kobayashi. We are really grateful to him.


I would like to talk a little about his important contribution to our Graduate School.

Our Graduate School of Mathematical Sciences was established in 1992, uniting two Departments of Mathematics, one in the Faculty of Science, and the other in the College of General Education. In 1993, the first Dean of our Graduate School, Professor Takushiro Ochiai decided that the newly born Graduate School should be passed under the external evaluation. I did not know what is the external evaluation at that time. In 1993, the evaluation committee was organized. It consists of Professors Shochichi Kobayashi, Frederic Gehring and Jerry Kazdan. Our Dean, Professor Ochiai asked Professor Kobayashi to serve as the chairman of the committee and Professor Kobayashi kindly accepted it.

For this evaluation, we prepared the Statement of Department in the beginning of the year 1994. Professor Kobayashi arrived in May 1994 and he began preparing the evaluation process. Then in August 1994, Professor Gehring and Professor Kazdan arrived, and the committee began working. The committee interviewed many faculty members, many students and people in other organizations for reference. This interviewing lasted for one month. I was one of the youngest professors at that time and a little involved in this reviewing process. I was also interviewed by the committee and I explained the activity of our Graduate School at that time.

By the effort of Professor Kobayashi, the committee wrote up the Report of the Review Committee in October 1994. The report is nicely and clearly written and in fact it is a very precious gift for us. The report does not contain bitter criticisms but it contains a lot of constructive recommendations for the future of the Graduate School. In fact it is filled with love for the mathematics and mathematicians. It was at the time when the first part of this building of Mathematical Sciences was under the construction. Until now, some important part of the Recommendations has been realized. But I think the report still guides us to make our School more competitive.

In 1997, Professor Shoshichi Kobayashi kindly took part of the evaluating committee for the education of mathematics for the freshmen and sophomores. He left us a very valuable report again. The recommendation he left is not really realized yet, and we need to consult it again to find the solution for the better education. We are very grateful for these two reports.


More academically, Professor Shoshichi Kobayashi appeared in seminars or meetings at our Graduate School quite often. When he appears, he was in the Kobayashi style, that is, he sat smiling in a very calm and gentle manner. Today, it is sad that we do not have him in this auditorium but I hope that he should be satisfied to see that the auditorium is filled with his mathematical legacy.


To close my address, I would like to expect that all the participants of this memorial symposium enjoy mathematics and find a new direction of research which Professor Shoshichi Kobayashi might have thought of, and this symposium will be remembered as an important symposium in the future.


Thank you very much for your attention.
