A Bimonthly Email Newsletter from the International Mathematical Union
Editor: Mireille Chaleyat-Maurel, University Paris Descartes, Paris, France
Beginning of September 2014, I attended the General Assembly of the International Council for Science (ICSU) in Auckland, New Zealand. The members of ICSU are national members and international scientific unions. Together with Manuel de Leon, I represented IMU at this General Assembly. Cheryl Praeger was also present, representing Australia.
Elections of the coming Executive Board (EB) for the next three years took place during the General Assembly. Three mathematicians were elected on the Executive Board of ICSU: Daya Reddy (South Africa) is the new President-elect (he will become President in 2017), John Ball was renewed as regular member of the EB for the coming three years, and Manuel de Leon was elected regular member of the EB: Manuel de Leon just finished eight years on the Executive Committee of IMU, during which he was the official representative of IMU at ICSU.
The International Council for Science is very little known among mathematicians. To my opinion, ICSU deserves to be better known, and this is why we will try to have a regular item on ICSU in each IMU Newsletter. ICSU's mission is to strengthen international science for the benefit of society. It promotes freedom and responsibility in the conduct of science, and IMU often refers to ICSU's statements when dealing with infringements to human or scientific rights. ICSU is also very involved in science and policy to ensure that science is integrated into international policy development. For that reason, the General Assembly was preceded by a two-day "Science Advice to Government Conference" (see http://www.globalscienceadvice.org/). Also, ICSU has increased its involvement in supporting research on understanding the planetary issues of climate change and sustainability, adapting to them, and linking research on the matter with policy. This has led to the creation of the 10 years initiative, Future Earth, which is the flagship program of ICSU. The past president, Yuan Tseh Lee, committed a lot of energy during his mandate to do fund raising for supporting Future Earth. I discussed with Frans Berkhout, the interim Director of Future Earth, and we are both convinced that mathematical sciences have an important role to play in Future Earth. The General Assembly is preceded by a one day meeting of the scientific unions, which is an opportunity of meeting our sister unions, learn about their activities and priorities, and start networking for joint activities.
The General Assembly of ICSU contains some invited scientific lectures. I was especially struck by the lecture of Nancy Bertler from the Antarctic Research Centre of New Zealand. We regularly hear about the sea rise during the 21st century. This rise has two origins: the melting of glaciers and the thermic expansion of the oceans. The melting of glaciers could produce an incredible amount of additional water: if all Antarctica and Greenland's glaciers were to melt, we could have a rise of the oceans of the order of 70 meters. What saves us in the short term is that the glaciers cannot melt so fast. But pay attention next time you hear the forecasts of sea rise: they never go past 2100! The lecture of Nancy Bertler dealt with a new potential component of the climate change, namely the potential "collapse" of Antarctica.
Because of the enormous weight of Antarctica's glaciers, most of the floor of these glaciers is below sea level. Hence, there is a potential of water penetrating under the glacier and causing the breaking the big pieces that would end floating and hence, rise the sea level. The recent studies conclude that such collapses could lead to a sea rise of 4 to 8 meters before the end of the century, much higher than the forecast of 0.5-1 meter rise in the last IPCC report. All climate studies rely on mathematical modelling. We, as mathematicians, develop tools to study models. But, what should be included in the models? This is one of the big challenge of climate science, which requires our collaboration with the other disciplines.
Ordinary member of the Executive Committee of IMU
Call for nominations for the Program Committee of ICM 2018
The next ICM will take place in Rio de Janeiro in 2018. The General Assembly of the IMU decided at its recent meeting in Gyeongju, Korea, that "The IMU Adhering Organizations should be invited to make suggestions for possible members of the Program Committee.", see Resolution 7 at
The community is hereby invited to propose members for the PC for ICM 2018 and to forward them to IMU through an Adhering Organization.
A proposal should include a brief letter of recommendation as well as a CV of the candidates [pdf-format only]. Candidates should not be contacted prior to the nomination, as the composition of the PC (except its chair) will only be made public at the ICM2018. The deadline is March 1, 2015, and proposals should be sent by an Adhering Organization to
CEIC Notes and Comments: ArXiv millionth paper
A relatively quiet, but notable, milestone was celebrated this past fall, as managers of arXiv.org at Cornell University counted the 1 millionth research article uploaded to the server. For mathematicians, the arXiv preprint server is a vibrant resource, showing continued growth in use by this discipline. Currently 28.8% of submitted papers are in mathematics or mathematical physics, and 15.1% are in computer science. More information on growth by topic at http://arxiv.org/help/stats/2014_by_area/index
Originally supported by Cornell University Library (CUL), arXiv has moved to a collaboratively governed, community-supported resource. Indeed, the growth of arXiv has led to new needs in underlying technology, as well as a plan for sustaining the service, which requires permanent staff and a $1M budget. In the new model, effective January 2013, arXiv is supported by libraries and research laboratories worldwide that represent arXiv's heaviest users, as well as by CUL and by generous matching funds from the Simons Foundation. See:
For a useful retrospective on these developments, a listing of the Membership Advisory Board and Scientific Advisory Board of arXiv, as well as a sketch of financials associated with the support structure, please see Cornell’s press release, and associated links:

International Year of Light and Light-based Technologies 2015
The United Nations have declared 2015, the International Year of Light and light-based technologies (IYL2015): www.light2015.org. The Opening Ceremony took place at UNESCO on January 19-20 2015:
The theme of light has many connections with mathematics and you could consider using the opportunity of this international year to highlight the contributions of mathematics in the study of light and its applications. If you are inspired and decide to organize to organize some event related to mathematics and light, then consider also posting it on the IYL2015 website by clicking on "Submit an event" at
Here are some relations between light and mathematics, from elementary ones to be used in education to more advanced ones in research. Fermat's principle states that the path of a ray of light between two points is the path that can be traversed in the least time: this principle unifies the laws of reflection and refraction. Mirrors having the shape of conics and optical lens are sources of nice mathematical problems. Optical fibers are now widely used in worldwide communications. Interference between beams of light are at the origin of iridescence. Mathematical modelling allows producing holograms with laser beams. Laser filamentation, a nonlinear regime, has potential applications in atmospheric remote sensing and lightning guiding. The 2014 Nobel Prizes in Physics and Chemistry were both related to light. The Nobel Prize in Physics celebrated the invention of blue light-emitting diodes, which has allowed bright and energy-saving white light sources, thus contributing to energy saving. The achievements of the winners of the Nobel Chemistry Prize allow to now peer in the nanoworld.

Interested candidates may contact the AvH any time at firstname.lastname@example.org.
A Newsletter for IMAGINARY
IMAGINARY, originally an an open-source traveling exhibition to popularize mathematics, has turned into a comprehensive platform to support math communication. All those working on math outreach are invited to join the new "Math Communication Network" initiated by IMAGINARY. This network aims to provide services to exhibitors, museums, performers, freelance math-artists, etc. See http://imaginary.org/network for more information.
In particular, there is a newsletter for the network with all the relevant news in the math communication field. Additionally, IMAGINARY has its own dedicated newsletter for the news and projects of the IMAGINARY exhibitions. Check
