The conference Mathematics Days in Sofia (MDS) is organized by the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences in collaboration with the Union of the Bulgarian Mathematicians and the Faculty of Mathematics and Informatics of Sofia University. The purpose of this event is to present the latest scientific achievements in the field of Mathematics and Informatics.

One of the main goals of the MDS conference is to bring together Bulgarian mathematicians and computer scientists working all over the world. In this way, the event will enrich the relations between the mathematicians working in Bulgaria and the Bulgarian mathematical diaspora.

The first edition of MDS was held in 2014 at the initiative of a number of prominent Bulgarian mathematicians working in Bulgaria and abroad and attended by more than 300 participants from all over the world. The second conference was organized in 2017, thus making MDS a traditional meeting of Bulgarian mathematicians working in Bulgaria and abroad with their colleagues from prestigious scientific centers all over the world. The third conference was planned for 2020, however it was canceled due to the COVID19 pandemic and its complications.
