21. In Memory Of Kiiti Morita And he left a legacy for japanese mathematicians, in particular, where it isestimated that more than half of the Japanese topologists today are directly or http://www.ams.org/development/mor-jhe.html

In Memory of Kiiti Morita John Ewing August 4, 1998 We are here today to honor a respected and eminent mathematician, Kiiti Morita, who passed away exactly three years ago, on August 4, 1995. I'd like to welcome our guests today, Professor Morita's widow, Tomiko; his son, Yasuhiro; his wife, Hiroko; and their son, Shiego. They flew here, some 6,740 miles (that's 10,871 kilometers!) to be with us today as we honor Professor Morita and dedicate our front garden area in his name. It is a strange feeling for me to be here today, saying these words. Before coming to the AMS, my field as a mathematician was Algebraic Topology. Professor Morita was a world class mathematician, who combined profound work in topology with brilliant insights into algebra. I grew up as a mathematician learning the phrase "Morita equivalence", a term that is everywhere in algebraic topology; I learned the concept long before I ever associated it to a person, the man who invented the idea in 1958. I learned of his other work in topology in a series of lectures while I was still a graduate student, but I never knew anything about the man behind those ideas. And having read more about the man, I wish I had known him, and not just his ideas. Looking at his long and distinguished career in mathematics, I am reminded of Shakespeare's famous quote:

Gossips and Rumors among Japanese Mathematicians... We thank the speakers and the audiences who attended the workshop NORTh 4 . I have enjoyed every lecture, and the series of lectures given by Professors Manivel and Sommers were just wonderful. Prof. Manivel introduced Vogel 's idea of universal Lie algebra, which seems wild (and at the same time very attractive) to me. There are three lines in the projective plane; on one of which sl_n lives, on another one sp_n and so_n live. On the other line, all the exceptional Lie algebras including so_8 and sl_3 live. Their intersections are sl_2=sp_1 , so_8 and sl_3! Also, between E_7 and E_8, there lives E he told. [Thu Mar 4 14:13:00 JST 2004] The newest issue of Ramanujan Journal is Rankin Memorial Issues.

Ishikawa S. Izumi S. Izumyia T. -C. Kuo K. Miyajima A. Neeman P. Norbury Organisers: Laurentiu Paunescu Adam Harris Satoshi Koike Toshizumi Fukui The Japanese-Australian Workshop on Real and Complex Singularities is an initiative towards the further advance of scientific exchange between Australian and Japanese researchers, and is made possible with the support of the Australian Mathematical Sciences Institute (AMSI). The scientific programme will be based around a series of expository lectures presented by the invited speakers, each of whom is an internationally recognised expert in an area of mathematics having substantial interactions with the contemporary theory of singularities in real and complex geometry. Each invited speaker will be asked to present two or three lectures on a topic of current interest, but in a manner which is accessible to non-experts in the field. The central aims of the workshop are: (1) to promote interaction between Australian and Japanese mathematicians, specifically in the field of singularity theory;

After graduating he entered Osaka Imperial University (later named Osaka University) where he was taught by Kenjiro Shoda , among others. These were difficult years for anyone to be studying in Japan and the next few years, as World War II drew to an end, would be even more difficult. He graduated with the degree of Bachelor of Science in September 1942. Matsushima was appointed as an assistant in the Mathematical Institute of Nagoya Imperial University (like Osaka and other Japanese universities it would soon drop the name "Imperial" from its title) immediately he had received his B.Sc. degree, and he was in post in time for the 1942-43 academic year. There were major difficulties in carrying out research in these war years since, quite apart from military reasons and problems caused by bombing, international mathematical journals were not reaching Japan. Equally, it was very difficult for Japanese mathematicians to publish the results that they were discovering. The first paper which Matsushima published contained a proof that a conjecture of Zassenhaus was false.

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.

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

dialogue with M. Yamaguchi regarding the authenticity of Sacks' claims Makoto Yamaguchi of Waseda University’s Department of Educational Psychology in Japan contacted me on 27/05/05: Oliver Sacks' report on a autistic twin generating large prime numbers is astonishing, which is also introduced in your website However, some Japanese mathematicians raised doubt. They claim that there cannot have been a book containing prime numbers of up to ten digits: Considering the vast number of the primes, they could not be contained in a book. I would appreciate your opinion. Do you know such a book published in your country? My reply: This is interesting. I have not looked into this. It is possible Sacks had a book containing *some* (but not all) 10 digit prime numbers. I will have to re-read his chapter, and give this some thought. Have the Japanese mathematicians raised these doubts in a published work, or just privately in conversation? Yamaguchi replied that they raised doubts in a Japanese-languge Internet forum. Before I had a chance to look into this, Dr. Yamaguchi contacted Oliver Sacks himself to ask about this matter. Here is part of Sack's assistant(?) Kate Edgar’s response, as forwarded to me on 28/06/05:

1."My lady, take Fermat into the music room. There will be an extra spoonful of jam if you find his proof." Tom Stoppard in Arcadia is just one of many who have helped to immortalise Fermat's Last Theorem as the Greatest Unsolved Problem of Mathematics. But last week in Jerusalem, it was Andrew Wiles, and not Arcadia's Thomassina, who was claiming that spoonful of jam. His solution of Fermat's Last Theorem was rewarded in the Knesset with one of mathematics highest accolades, the Wolf prize worth $100,000. 2.But with its solution, have we lost the magic that this puzzle has generated over the centuries? Mathematics has benefited so much from the adoption of Fermat into the public imagination as Mathematics' Holy Grail. Fermat is probably responsible for more school children going into mathematics than any other problem. Wiles himself explained how "here was a problem that I, a 10-year-old, could understand, but none of the great mathematicians had been able to resolve. From that moment I tried to solve it myself." 3.Could anything possibly replace Fermat's Last Theorem as Mathematics' great unsolved problem. Most people believe that mathematical research is long division to a lot of decimal places. With the advent of the computer, surely mathematics must have all been worked out by now. So is that the end of Mathematics?

Fermat's Last Theorem by Dino Surendran Mathematians do not often make it into the world's press. But in 1993, Andrew Wiles, a British maths professor at Princeton University, hit the headlines. His feat? Showing that there are no integer solutions to the equation x n + y n = z n when n is an integer greater than 2. In other words, he had proved Fermat's Last Theorem This problem was written down around 1637 by Pierre de Fermat, a French lawyer in Toulouse who was also a prominent amateur mathematician. He was reading a textbook when a thought occurred to him. He decided to write it down before he forgot it - and the nearest piece of paper was the margin of the said textbook: ``On the other hand it is impossible for a cube to be written as a sum of two cubes or a fourth power to be written as the sum of two fourth powers or in general, for any number which is a power greater than the second to be written as a sum of two like powers. I have a truly marvellous demonstration of this proposition which this margin is too large to contain.'' Now, it is suspected that he later found that his proof was incorrect, since he only ever

Next: Classic Books on Up: Game Theoretic Analysis Previous: ``Winning Poker Systems'' Other Mathematical Studies Although game theory would seem to be the natural mathematical discipline for the study of poker, a number of other specific mathematical problems arising from the game have also been studied. Many of these are only tangentially related to the core problems being addressed by strategic game playing, but are still worth looking at, if only for the sake of completeness. Two Japanese mathematicians, Minoru Sakaguchi and Setsuko Sakai, are responsible for most of the work on these loosely related topics. Some of the problems they have looked at include the effects of partial information [ ], multi-stage poker [ ], the disadvantage of being the first player to act in a given betting round [ ], and a few of the subtleties encountered with more realistic poker models [ ]. Notwithstanding the highly specialized nature of these problems, a few of their mathematical ideas might be incorporated into algorithmic analysis techniques. More optimistically, the purely mathematical approach may eventually produce some tangible dividends for poker practitioners. For example, in one of their most recent articles, Sakaguchi and Sakai solve (from a purely mathematical standpoint) some of the fundamentally difficult problems in three-person playing scenarios [ While these papers may be of limited practical value, it is important to maintain a mathematically precise view of the game. Toward this end, some background in probability theory is essential for academic poker researchers. While this knowledge can be acquired in many ways, one strongly recommended reference is ``The Theory of Gambling and Statistical Logic'', by Richard Epstein [

37. NATFHE Says Important work was done too by japanese mathematicians immediately after the war.For me, this was the cliche, the book I could not put down. http://www.natfhe.org.uk/says/bookrevs/mat/mat00001.html

text version NATFHE SAYS PUBLICATIONS THE LECTURER ... MATHEMATICS Fermat's Last Theorem Simon Singh Fourth Estate Rarely does a book on mathematics reach the top ten best sellers list. Yet FERMAT'S LAST THEOREM has achieved precisely this. Singh's book is for pure mathematics what Hawking's A BRIEF HISTORY OF TIME is for applied mathematics. 'I have truly marvellous demonstration of this proposition which this margin is too narrow to contain.' These words, written in the margin of a mathematics book by Fermat, sparked off a search, taking over 350 years, to find a proof. The beauty of Fermat's Last Theorem is that it can be easily stated, such that a ten year-old can understand the problem, but the solution is so difficult to find. The conundrum taxed the greatest brains of mathematics. Singh's account keeps the mathematical content to a minimum (largely in appendices), while emphasising the biographical details of the giants of mathematics. The formulation of the problem can be traced back to Pythagoras, the seed of the solution to Euclid. The problem was finally solved by Andrew Wiles, a forty-something mathematician, who announced a proof at a lecture in Cambridge in 1993, which was then revealed to contain a flaw. This took another 18 months to unravel, and has then taken two years for Wiles's peers to verify. The problem had inspired Wiles to take an interest in mathematics ever since he read of the problem as a ten-year old in a library in Cambridge.

Fermat's last theorem was originally not as much of a theorem as it was a conjecture. Pierre de Fermat was a 17th Century French lawyer who spent his spare time thinking about number theory . He made a note in his copy of Bachet's translation of Diophantos' Arithmetica , next to the posed problem of finding all solutions to the equation in Pythagoras theorem. It seemed to him that the generalised problem of finding integer solutions a,b,c to the equation a n +b n =c n was impossible, provided that n is an integer larger than two; and that he had found a demonstrationem mirabilem - 'a marvellous proof' - but that hanc marginis exiguitas non caperet , 'this margin was not able to contain it'.

Home Outline Participants Programme London Mathematical Society Durham Symposium Methods of Integrable Systems in Geometry Friday 11th August - Monday 21st August 2006 Outline Relations between differential geometry and integrable systems can be traced back more than a century, but it was only recently that methods of integrable system theory have been consistently applied to obtain global geometrical results. These methods include insights gained from soliton theory in the 1970's, ideas obtained from mathematical physics in the 1980's and the sophisticated recent tools from algebraic geometry, representation theory, and the theory of infinite dimensional manifolds. Some of the major highlights of this area are the remarkable geometry of the KdV equation (and other soliton equations), the analysis of classes of surfaces (such as CMC surfaces and harmonic maps) by means of spectral curves and loop groups, and the theory of discrete integrable systems (aided by state of the art computer visualization and experimentation). Substantial contributions have been and are being made by British mathematicians. The wide spectrum of problems being studied and the pioneering nature of the subject have led to a need for greater cohesion. Goals The purpose of this symposium is to bring together leading researchers for a 10 day period of concentration, consolidation and cross-fertilization. This will allow the experience and progress made by each group to support the work of other groups. As the first high profile conference in the UK on this topic, it will greatly strengthen the network of core researchers in the UK. Regional cooperation (identified as a structural issue in the recent International Review of UK Research in Mathematics) will be stimulated as UK researchers in the area of the symposium are spread widely throughout the country.
