Agenda of ICM-11

Download agenda (pdf; 102 kiB; as at 2019-05-14)

Note: In a change to the structure of ICM-10 and in partial response to feedback from Secretariat, ‘Site Perspective’ slots have been introduced. The aim is to facilitate topic-focused talks presented by sites in context rather than as part of a separate session. Sites will still have the same amount of time overall for talks as in ICM-10.
