“Mathematicians Who Lost Their Faces—Essays in Idleness on Mathematics,” (Iwanami Publisher, July 2013)

BookCoverA collection of essays (in Japanese) by Shoshichi Kobayashi entitled “Mathematicians Who Lost Their Faces—Essays on Mathematics in Idleness “ will be published by Iwanami Publisher on July 30, 2013.

From the Publisher’s flier:

The first essay by the author of internationally known accomplishments in research on differential geometry and complex manifolds. This collection of small pieces with the title “Essays in Idleness on Mathematics (‘Suugaku Tsurezure’)” has become his posthumous work, without being completed. By reading his essays on the real images of mathematicians, how mathematical symbols were created, what is “Beauty of mathematics,” we sense the author’s deep thought on mathematics and mathematicians.

Message from the Editor of Iwanami Publisher:

Professor Shoshichi Kobayashi who is internationally recognized for his achievements in research on differential geometry and complex manifolds passed away unexpectedly in the summer of 2012. This manuscript was originally prepared for publication in our Science Library Series. Our intention was to ask Professor Kobayashi to “cook” various topics on mathematics from his point of view so that the general reader can taste fun of mathematics, and joys of mathematical thinking.

In the spring of 2012, I received a package from him. The enclosed letter said, “This manuscript is yet to be completed. I would like to spend more time to polish and finish it by the end of this year. I am sending you this copy as my progress report.” From the manuscript handwritten on Japanese writing pads filled with his familiar writing style, I sensed his personality. While I was looking forward to the completion of the manuscript , I was informed of the saddening news of his unexpected demise. That bundle of copies received in the spring turned out to become a posthumous manuscript.

Although he considered the manuscript to be incomplete, I consulted with his family members and his close associates and have turned it into this book, for which I would like to thank many individuals.

” 数学との出会い”をテーマに、小社は『この数学書がおもしろい』『この定理が美しい』の2冊を刊行しました。本および研究分野との出会いに焦点をあてまし たが、数学にとってもう一つ大きな要因は数学者との出会いであると思われます。そこで今回、3部作のまとめという位置付けで、数学者との出会いをテーマに 本書を企画致しました。

良い先生・良い数学者に出会うことは、数学を志すときに非常に大きな要素であると言われます。数学者に魅了されて研 究分野を選ばれた人も多くいらっしゃることと思います。出会いのエピソード、影響を受けたこと、数学者として学んだこと・魅了されたこと、人間としての交 流などなど語れば尽くせないものが数多くあるのではないかと考えました。そこで、16人の数学者のかたに、ご自身にとっての”この”数学者との出会いをご 自由にお書きいただきました。併せて、これから数学を目指そう、あるいは、いま目指している若いかたを読者として意識していただくことも御願いを致しまし た。
