An invitation to give a plenary lecture to the thousands of ICM participants is considered a special distinction in the mathematics profession. The Program Committee selects the plenary lectures for the ICM very carefully. Traditionally, they occupy the morning half of the program, drawing the attention of all ICM participants and thousands of other mathematicians via live stream. Each lecture begins with the introduction of the speaker by another world-renowned scholar who chairs the session.
The ICM website will have special supplementary materials for each plenary lecture. These materials will help attendees learn more about new developments and areas of mathematics that may be off the beaten track. Lectures will be published in the ICM proceedings and freely available online.
