The next International Congress of Mathematicians will take place in Seoul, Korea, from Wednesday August 13, through Thursday August 21, 2014. We welcome our colleagues from around the world to the congress, and very much hope that you will also be able to attend ICM2014 and savor some of the fine attractions that our country offers. 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 city where the traditional and cutting-edge coexist side-by-side in perfect harmony. Family-friendly ICM Seoul is filled with great family-friendly activities. For the participants who are accompanying family members, we introduces a course that connects some of Seoul?s best destinations for the traveling family.
