The pre-registration process for ICM 2014 is underway. If you have not yet pre- registered, please do so by following the simple instructions at http://icm2014.org. The ICM e-News is being circulated to peo- ple who have pre-registered for the congress. We strongly recom- mend that you visit the homepage regularly for updated informa- tion and ICM related activities. We look forward to welcoming you to the congress in Seoul. In the centre of Seoul Korea, with a five-millennia-long history, is an attractive place to visit and Seoul, the capital of Korea for over 600 years, is a vibrant, modern city with a population of 11 million, where traditional culture and cutting-edge trends co-exist in perfect harmony. With a low crime rate and a state-of-the-art subway system, it is one of the safest cities in the world. The congress venue, Coex, is at the heart of downtown Seoul, located right next to a subway station. There are over 7,500 hotel rooms within 5 km of Coex. Family-friendly ICM Seoul is full of great family-friendly activities. For the accompanying family members of the ICM participants, an on-site childcare facility will be available. And we recommend some of Seoul's best destinations for the family { from a day at a theme park to outdoor events for youngsters and countless playgrounds in the heart of downtown. Three Disney- style theme parks (LOTTE WORLD, SEOUL LAND and EVERLAND) are around 10 minutes to 1 hour bus/subway ride from central Seoul. Especially during Summer season, all the theme parks are open until late at night performing fantastic laser shows and fireworks shows. Bring your family to Seoul ICM and experience wonderful festivals and IAMP News Bulletin, October 20133 Hyungju Park magnificent shows at the theme parks in Korea! Family-friendly ICM will make your journey all the more special. NANUM 2014 To make the congress a true worldwide gathering, the Organising Committee places spe- cial emphasis on supporting mathematicians from developing countries. Members of the Korean Mathematical Society fully acknowledge the gracious support received from the international mathematical community in the 1970s and 1980s and hope more countries can share in the benefits. This has motivated the theme of Solidarity in Mathematics and 1,000 mathematicians from developing countries will be invited to Korea during ICM 2014. Many of these mathematicians would not have been able to visit an ICM otherwise and stand to take the ICM excitements and new knowledge back to their home coun- tries. The Seoul ICM Travel Fellowship Fund was set up for this purpose and the fund is expected to receive over 2,000,000 USD by 2014, mainly from global corporations and in- dividual donors. By collaborating with IMU/CDC, we are developing selection guidelines for this travel assistance programme, called NANUM 2014. NANUM is a Korean word meaning gracious and unconditional sharing. A selection policy integrating age, gender and geographical balance is being carefully crafted. NANUM 2014 in detail Criteria • Priority will be given to applicants from countries with a GDP of $ 7,500 (nominal) or less. • Some underdeveloped regions inside ineligible countries will be included. Composition of the 1,000: • 45% senior mathematicians, 45% junior mathematicians, 10% advanced graduate students. • Math School for 100 (tentative). • At least 100 female mathematicians. The applications will be reviewed by five review committees covering the following five regions: • Africa. • East and Southeast Asia including China and North Korea. • South and West Asia including the Indian subcontinent. 4 IAMP News Bulletin, October 2013 International Congress of Mathematicians 2014 in Seoul • Eastern Europe including North Asia. • Central and South America. Timeline of the application and selection procedure: • 28 Feb 2013: selection of 48 international NANUM ambassadors. • 10 Jun 2013 31 Aug 2013: applications received. • 31 Dec 2013: review of applications completed. • Jan 2014: notification of acceptance. MENAO A MENAO event (MENAO stands for Mathematics in Emerging Nations: Achievements and Opportunities), which features about 100 participants and discussants and is open to an additional 350 observers, will take place on the day immediately preceding the opening of the congress. The goal of the MENAO event is • To listen to the voices of mathematicians and aspiring advanced students of math- ematics from the developing world. • To share success stories of development via partnerships between the local mathe- matical communities, their governments and international agencies and foundations. • To review the current status of those efforts and future needs. A detailed programme will be developed and distributed by the IMU. Invited plenary, sectional and special lectures The privilege of sending the invitations belongs to the Organising Committee whereas it is the privilege of the Programme Committee to select the invited plenary and sec- tional speakers for the congress. Plenary lectures are invited one-hour lectures to be held without other parallel activities. The lectures should be broad surveys of recent major developments, aimed at the entire mathematical community. Sectional lectures are invited 45-minute lectures. Several sectional lectures are scheduled in parallel. The ICM Emmy Noether lecture honours women who have made fundamental and sustained contributions to mathematics and the ICM Emmy Noether lecturer has been chosen by a committee appointed by the IMU Executive Committee. All the invitations have been sent out by the Organising Committee, and hopefully they have them in hand by now. IAMP News Bulletin, October 20135 Detlev Buchholz How time cures infrared problems by Detlev Buchholz (G¨ottingen) Detlev Buchholz received his PhD from the University of Hamburg in 1973. Having held postdoc positions at CERN in Geneva and at the University of California in Berkeley he became Professor of Theoretical Physics at the Univer- sity of Hamburg in 1979. In 1997 he accepted a call from the University of G¨ottingenwhere he stayed until his re- tirement in 2009. He has established important conceptual and methodical results in quantum field theory such as a collision theory for massless particles, a quantitative de- scription of phase space properties which allowed him to prove the causal independence of observables and existence of thermal equilibrium states in these theories, a compre- hensive classification of the possible sector structure and statistics of massive theories and a general method for short distance analysis. From 2000 to 2005 he was Editor{ in{Chief of Reviews in Mathematical Physics and he is presently associate editor of three other journals. For his scientific work he was honored by several awards, notably by the Max Planck Medal of the German Physical Society. The understanding of the sector structure of the physical state space in quantum field theories with long range forces, such as quantum electrodynamics, is a longstanding problem. Recall that a superselection sector is a subspace of the physical Hilbert space of all states of finite energy on which the local observables act irreducibly. So the global superselection observables have sharp values in a sector and the superposition principle holds unrestrictedly there; states in different sectors cannot coherently be superimposed, however. The presence of long range forces leads to an abundance of sectors which carry the same total charge, but differ by multifarious clouds of low energy massless particles which are formed in collisions of the charged particles. In computations one frequently copes with this problem by some ad hoc selection of sectors, e.g. by picking a convenient physical gauge, and by summing over undetected low energy massless particles.
