About

The first edition of the International Meeting of Young Researchers in Singularity Theory and Related Fields was held at IMPA, Brazil, from 02 to 07 March 2020, as part of the Thematic Program in Singularity Theory. The second edition will happen online, from 07 to 11 February 2022, as part of the 50 years celebration of ICMC and as part of the Summer 2022 Program in Mathematics of the ICMC.

This event aims to bring together as speakers graduate students and young researchers from all over the world representing different subjects related to Singularity Theory.

The event will be free of charge. All participants need to register.
