As Madrid prepares to welcome mathematicians from around the world to
ICM 2006, it is worth reflecting on the immense amount of time, skill
and dedication that those involved in the organization, especially in
Spain, but also on the various international committees, have devoted to
the realization of this complex event. I have admired from afar many of
the preparations, but only those who have themselves worked on the many
different aspects of the planning (and their families) will really
understand the extent of the effort that they have made over the last
four years.  I have no doubt that as a result the Madrid Congress will
be of outstanding mathematical quality and excitement, and that it will
also successfully engage the general public by providing a window
through which to see the mathematical community and its importance for
the world. At the same time we applaud those who have sponsored the ICM,
without whose support the event would not be possible, and without whom
many participants would not have been able to attend.
    I wish all who come to Madrid a memorable Congress.

2. ICM 2006 NEWS

  1. His Majesty the King Juan Carlos of Spain will open the ICM 2006.
  2. More than 3300 people have now registered, and the registration is still open.
  3. Two new cultural activities:
    • A book exhibition in the old library Marques de Valdecilla, Universidad Complutense de Madrid. The bibliographical exhibition "History of Mathematical Knowledge", held by Universidad Complutense de Madrid in its Historical Library, intends to show the development of mathematical science through the texts that had been used in those institutions since the 16C. Colegio Imperial de los Jesuitas, los Colegios de Alcalá, el Real Colegio de Medicina y Cirugía de San Carlos and other centres and private libraries stored up books that have become a guide for us to know the way mathematics was studied and translated through the centuries. History has determined that they be kept in Universidad Complutense's Historical Library, one of Europe's oldest libraries.
    • An exhibition on Gödel. "Exposición Kurt Gödel, 1906-2006", Jardín Botánico de la Universidad Complutense de Madrid, 22 August - 8 September. Free entrance. It is based on the exhibition shown in Vienna.
    And also:
    • Exhibition "Experiencing mathematics!" This exhibition, initiated by UNESCO, will be presented in a site downtown in Madrid, Centro Cultural Conde Duque. It is sponsored by IMU and ICMI and planned by the Centre Science of Orléans (France). Centro Cultural Conde Duque, Conde Duque 9-11, 28015 Madrid, August-October 2006.

The Federated World Directory of Mathematicians (FWDM)

Once, long ago, one could check whether a person was an acknowledged
mathematician by looking her up in the World Directory of
Mathematicians. But the WDM is no more, a victim of costs and of the
coming of the electronic age. In retaliation, the CEIC now provides a
search engine, the FWDM, capable of searching, simultaneously, all those
Math Society membership lists that have made themselves appropriately
available. As a bonus, the FWDM also provides links to Google and Google
Scholar entries. Fourteen months ago (IMU on the Web #7) Alf mentioned
the 'first steps towards constructing' a Federated World Directory of
Mathematicians. Those steps became strides and by now have reached their
goal. Readers should check their personal details and, more important,
urge their national societies to make their membership lists accessible
to the FWDM.
One caveat: search engines can be unexpectedly stupid and stubborn. It
may be wiser to look for 'Alf*' rather than for 'Alf' and then to refine
one's search only if that leads to too many hits. 'Borwein' on the other
hand offers no such problems.

Past ICMI President Shokichi Iyanaga passed away on June 1st. Professor
Iyanaga was Vice-President of ICMI from 1971 to 1974, and President from
1975 to 1978.  He also served as a member of the first Executive
Committee of the International Mathematical Union, when the union was
re-established after the Second World War, from 1952 to 1954. Professor
Iyanaga celebrated his 100th anniversary on 2 April 2006.  On the very
same day, a substantial mathematical paper of Professor Iyanaga was
published online in the Japanese Journal of Mathematics:
Shokichi Iyanaga, "Travaux de Claude Chevalley sur la théorie du corps
de classes: Introduction."  Japanese Journal of Mathematics 1(2006), 25-85.
This paper is available via Open Access at
On the occasion of the 50th issue of the ICMI Bulletin, Professor
Iyanaga prepared a paper entitled "My remembrances from the period
1975-1978," ICMI Bulletin 50 (June 2001), pp. 6-7:
