The specific activities we will develop on the occasion of ICM 2022 in Paris are mainly a series of summer schools taking place right before or after the ICM. Although not completely dedicated to young mathematicians from developing countries, these summer schools will be designed to welcome them in optimal conditions. We see ICM 2022 in Paris as a great opportunity to offer these young colleagues access to state of the art knowledge in their fields of interest. Free of charge housing and travel support will be provided to summer school participants from developing countries, who will be also be exempt from registration fees at ICM.
