The 6th ICCM will be held from July 14 to 19, 2013 in Taipei. You are cordially invited to joint this great event! Please observe that this 2013 ICCM will be held in JULY, not in December as with the previous ICCMs. It is urgent to mark July 2013 now. 　　The sixth International Congress of Chinese Mathematicians (ICCM) July 2013 in Taipei. 　　　 Start: 08:30, July 14, 2013 　　　 End: 18:00, July 19, 2013 　　　 Opening ceremony: July 14, in the Big Hall of the Grand Hotel, Taipei. 　　　 Lectures and invited talks from July 15 to July 19 are on the campus of National Taiwan University, Taipei. 　　ICCM is a triennial event that brings together Chinese and overseas mathematicians to discuss the latest research developments in pure and applied mathematics. 　　During the opening of the ICCM 2013, you will witness the presentation of the Morningside Medals, the most prestigious awards for Chinese mathematicians. During the conference, there will be at least twenty plenary talks, several Morningside talks by international speakers, and over one hundred 45-minutes talks. The talks cover a full range of subjects in mathematical sciences, from number theory, geometry, differential equations to statistics and bio-mathematics. 　　The first Congress was held in December 1998 in Beijing. The second Congress took place in Taipei 2001, then in Hong Kong, in Hangzhou, and 2010 in Beijing again. After twelve years, the ICCM 2013 will return to Taipei. We expect that there will be about one thousand participants and nearly two hundred presentations on a broad spectrum of mathematical sciences. 　　The 2013 registration fee is USD100 (or USD 50) for each participant joining the formal Banquet (without joining the formal banquet respectively). 　　We have tried to allocate a limited amount of grant to support young people to ICCM, particularly those young Chinese mathematicians from less developed countries, the deadline for application is end of December 2012. Please upload the necessary documents upon registration.
