   Japanese Mathematical History In Japanese the word wasan exists, it is used to refer to Japanese mathematics. Wassan is meant to stand in opposition to western mathematics, yosan. seventeenth century that definite historical records exist of japanese mathematicians. The first of these is Kambei

   Extractions: RELATED LINKS Of the world's countless customs and traditions, perhaps none is as elegant, nor as beautiful, as the tradition of sangaku , Japanese temple geometry. From 1639 to 1854, Japan lived in strict, self-imposed isolation from the West. Access to all forms of occidental culture was suppressed, and the influx of Western scientific ideas was effectively curtailed. During this period of seclusion, a kind of native mathematics flourished. Devotees of math, evidently samurai, merchants and farmers, would solve a wide variety of geometry problems, inscribe their efforts in delicately colored wooden tablets and hang the works under the roofs of religious buildings. These sangaku , a word that literally means mathematical tablet, may have been acts of homagea thanks to a guiding spiritor they may have been brazen challenges to other worshipers: Solve this one if you can! For the most part

2. Japanese Theorem -- From MathWorld
   According to an ancient custom of japanese mathematicians, this theorem was a Sangaku problem inscribed on tablets hung

   Extractions: Let a convex cyclic polygon be triangulated in any manner, and draw the incircle to each triangle so constructed. Then the sum of the inradii is a constant independent of the triangulation chosen. This theorem can be proved using Carnot's theorem . In the above figures, for example, the inradii of the left triangulation are 0.142479, 0.156972, 0.232307, 0.498525, and the inradii of the right triangulation are 0.157243, 0.206644, 0.312037, 0.354359, giving a sum of 1.03028 in each case. According to an ancient custom of Japanese mathematicians, this theorem was a Sangaku problem inscribed on tablets hung in a Japanese temple to honor the gods and the author in 1800 (Johnson 1929). The converse is also true: if the sum of inradii does not depend on the triangulation of a polygon , then the polygon is cyclic Carnot's Theorem Cyclic Polygon Incircle ... Triangulation

   there are now quite a number of japanese mathematicians, but in those days, we had few colleagues.

   Extractions: Answers to Sangaku Problems The original solution to this problem applies the Japanese version of the Descartes circle theorem several times. The answer given here, though, was obtained by using the inversion method, which was unknown to the Japanese mathematicians of that era. Because the method of inversion is generally not taught in American math courses, let us first review the technique and state without proof the results needed to solve the problem. Inversion is an operation generally defined with respect to a circle, call it S , with a radius k and a center T . The point T is called the center of inversion. Let P be any point in the plane containing S , and let TP be the legnth joining points T and P If P' is the inverse of P with respect to S , then In other words, r is the geometric mean of the lengths TP and TP' . The reason is that by construction, triangles TAP' and TAP are similar and so TP/r = r/TP' or TP (TP') = r Not only pointsbut entire figurescan be inverted. Each point P on the original inverts to P' on the inversion. The following four theorems apply to a circle

This is the end of the similar works for type I dual pairs (by Moeglin, Adamas, Barbasch, and Paul) for "equal rank case". Although the description is quite complicated, these works seem to settle the problem of describing explicit theta correspondence considerably. [Fri Dec 8 18:13:47 JST 2000] There is an internatinal conference in honor of Prof. Schiffmann in January, 2001, in Strassbourg. It seems that it will be a very interesting conference, and many Japanese mathematicians will attend it. [Sat Dec 9 22:02:33 JST 2000] Prof. Mukai (Nagoya Univ.) has written two books on moduli theory (or geometric invariant theory) in Japanese. And now it is being translated into English. The contents are full of examples and very fascinating. There is no introductory textbook in geometric invariant theory other than Mumford-Forgaty-Kirwin (if one can call it a textbook). A book for beginners in this field is expected for a long time, to my impression, and now it will soon be available!! [Sat Dec 9 21:55:52 JST 2000] Encyclopedia of Mathematics (edited by MSJ) will be revised (4th edition) in next 4 or 5 years. It will become more comprehensive (^^;;) and the contents will be upgraded to certain extent.

I'm not really sure what you want to know about Japanese mathematics. If you want to know about modern teaching trends there, the article you already found is a great starting point and has numerous references itself which must be in turn cross-referenced themselves.

    Extractions: VOL. 29, NO. 27 Mathematicians from around the world will meet at Homewood on Friday, March 17, for the start of a 10-day international conference, an annual event co-sponsored by the Mathematics Department and the Japan-U.S. Mathematics Institute, known as JAMI. This year's conference will focus on recent progress in homotopy theory. The conference aims to facilitate interaction between the mathematicians working in homotopy theory, which is a branch of algebraic topology, and to allow them discuss recent developments. The JAMI program, inaugurated in 1988, continues the tradition of friendly relations and interaction with Japanese mathematicians. JAMI also has attracted the attention of European mathematicians, and consequently, the yearly conference has attained an international scale with scholars from Europe joining the American and Japanese participants. The conference is part of a semester-long special program that has attracted 11 visitors from Japan, who are staying for one to three months. Because of them and the strength of the department in homotopy theory, Johns Hopkins attracts faculty on leave in the field. Consequently, nine non-Japanese also have taken up residence in the Department of Mathematics during the three-month period. The program is organized by J. Michael Boardman, Don Davis, Jean-Pierre Meyer, Jack Morava, Goro Nishida, W. Stephen Wilson and Nobuaki Yagita with grants from the National Science Foundation and the Japan Society for the Promotion of Science.

Wells called the world’s best, most ‘scientific’ and the simplest) for my translation was the one, which had been devised for the new, forthcoming age, by the Korean Language Society, in itself a patriotic underground movement, some members of which died, or spent many years, in Japanese prisons.

The theme of this year's conference is linear and non-linear scattering, a popular area of specialty that has many theoretical as well as physical applications, including quantum mechanics. The annual conference is co-sponsored by the Department of Mathematics and the Japan-U.S. Mathematics Institute (JAMI), an exchange program that allows Japanese mathematicians to come to Hopkins to do research and become acquainted with math professors here. The program will be preceded on Tuesday, Wednesday and Thursday by an informal workshop dealing with scattering theory. The actual conference begins Friday, March 31, and continues through Monday. About 20 mathematicians will deliver lectures, which will be held in 205 Krieger Hall.

    Extractions: Recommend this site In Roger Johnson's marvellous old geometry text- Advanced Euclidean Geometry , first published in 1929 - he reports (on page 193 of the Dover edition, 1960) on the ancient custom by Japanese mathematicians of inscribing their discoveries on tablets which were hung in the temples to the glory of the gods and the honor of the authors. The following gem is known to have been exhibited in this way in the year 1800. Let a convex polygon , which is inscribed in a circle, be triangulated by drawing all the diagonals from one of the vertices, and let the inscribed circle be drawn in each of the triangles. Then the sum of the radii of all these circles is a constant which is independent of which vertex is used to form the triangulation (Figure 1). A great deal more might have been claimed, for this same sum results for every way of triangulating the polygon! (Figure 2). As we shall see, a simple application of a beautiful theorem of L. N. M. Carnot

    Extractions: Shizuo Kakutani 's father, Kakujiro Kakutani, was a lawyer. Shizuo was the youngest of the two sons in the family, the eldest being Seiichi who was eight years older. Seiichi studied physics at Kyoto University and it was through him that Shizuo was first introduced to mathematics. When he was about nine years old his elder brother, on one of his frequent visits back to his home while he studied at university, would explain mathematical ideas to him. Shizuo was fascinated and was enthusiastic to learn more mathematics. However two factors conspired to make this impossible. The first problem was that Kakujiro Kakutani had made the decision that one of his two sons would follow him into law and take over his practice in due course. Clearly Seiichi was training to be a physicist and not studying law so Shizuo would have to be the one to follow his father. The mathematics lessons from Seiichi were tragically cut short when he died of typhoid fever at the age of twenty. After completing his middle school, Shizuo entered Konan High School in Kobe to prepare for his university studies. At this stage he had to choose between arts subjects or sciences and his father gave him no choice since studying law at university required him to graduate from high school which qualifications in literature and arts. By the time Shizuo graduated, his father relented seeing that his son was so keen to study mathematics at university. However, Shizuo was now not qualified to enter a mathematics course at either Tokyo University of Kyoto University since these had absolute rules regarding entry qualifications.

    Extractions: Kenjiro Shoda was born in Tatebayashi in the Gunma Prefecture of Japan but he underwent schooling in Tokyo until he completed middle school. There were academies in Japan for the brightest pupils with the task of preparing them for a university education. Shoda, after showing great talents at middle school, attended the Eighth National Senior High School in Nagoya. After graduating from the Eighth High School, Shoda entered Tokyo Imperial University (the title 'Imperial' would soon be dropped from the name of all Japanese universities) and there he was taught by Takagi . This was an exciting period to study at Tokyo University for Takagi had published his famous paper on class field theory in 1920. Takagi lectured on group theory, representation theory, Galois theory, and algebraic number theory. When Shoda was in his final undergraduate year, his studies were supervised by Takagi and he inspired Shoda to work on algebra. Shoda graduated from the Department of Mathematics at Tokyo University in 1925 and began his graduate studies under
