Welcome to the International Congress of Mathematicians 2018 (ICM 2018)

From August 1st to 9th, 2018, Rio de Janeiro will host the International Congress of Mathematicians (ICM) in its largest and most traditional convention center: Riocentro, in the Barra da Tijuca neighborhood.

During these nine days, some of the world’s best researchers in Mathematics and related areas will come together to share knowledge and take part in various activities, from prizes and technical talks to outreach events. Participants will also be able to enjoy Barra da Tijuca, with its lush landscape of beaches, mountains and lagoons, and its manifold leisure options.

Since 1897, the International Congress of Mathematicians has helped shape the history of mathematics in the 20th and 21st centuries. As the first edition of the ICM in Latin America, as well as in the Southern Hemisphere, the ICM in Rio de Janeiro will give us an opportunity to reflect on the great progress of the region in terms of research and public awareness of mathematics.

It is a pleasure to invite you to attend ICM 2018, in Rio de Janeiro. This site has the information you need for planning your trip to ICM and enjoying your stay in Brazil, a country with many memorable attractions and far beyond what the conference has to offer.

See you in Rio!

Chairman of the ICM 2018 Organizing Committee
