Message from the President of ICIAM

The ICIAM 2023 congress is approaching. It will be held in Tokyo, the capital of Japan, from August 20
to 25, 2023. According to the congress organizers, it is expected that the number of participants will reach about 5000, which will make ICIAM 2023 bigger than any previous ICIAM congresses. The number of submissions for mini-symposia has also reached a new record, above the previous Beijing and Valencia congresses.  That shows the interest of the community to attend the congress and participate in its scientific program. Apart from the mini-symposia, we will have a beautiful series of invited talks, selected by a high-level international scientific committee, led by Professor Yasumasa Nishiura. There will also be the Olga Taussky-Todd Lecture lecture delivered this time by Professor IIse C.F. Ipsen and two public lectures, by Prof. Noboru Kikuchi and Prof. Padmanabhan Seshaiyer respectively.  There will also be all the conferences organized within CSIAM, JSIAM and SIAM annual meetings, that will be embedded into the congress. The ICIAM prize lectures will complete the scientific program, and I assume that there will also be prize lectures organized by SIAM, corresponding to its prizes. All that certainly means a large number of very interesting talks. The complete program, that contains also an industry day, can be consulted in the congress website (

This year's ICIAM Board meeting will take place on August 26th 2023, right after the end of the congress. Several important decisions will be made in this board meeting, including the election of four Officers (the Treasurer and three officers at large) and the choice of the Scientific Program Committee (SPC) for the next congress (The Hague, 2027), whose chair will be Professor Barbara Wohlmuth. The organizing committee of ICIAM 2023 will also present a first report about the congress.

Similar to what ICIAM has been doing in previous congress years, the day before the beginning of the congress, there will be a meeting of the presidents of member societies present in Tokyo. This meeting is naturally less formal than the Board meeting, has no particular rules for its agenda, and the main goal is to discuss ICIAM matters of interest to every society, as well as to find possible new activities that could enrich the current list. That meeting will take place on August 20th, 2023.

I am sure that ICIAM 2023 will be a great success, and I look forward to seeing many of you in Tokyo in August!
