A Consortium Distinguished Lecture Series by Ivan Dimitrov (Queen's University, Canada) on root systems, their generalizations, and applications to hyperplane arrangements and inversion sets of roots — May 19, 21 and June 1, 3, 5, 2026, ICMS-Sofia (Room 403) and via Zoom.

The conference aims to bring together leading senior researchers and promising early‑career scholars working in elliptic and parabolic partial differential equations. Key topics include regularity theory and its applications, free boundary problems, singularity formation and qualitative properties of solutions. A particular emphasis will be placed on fostering participation from young scholars in Eastern Europe, providing them with the opportunity to engage with cutting-edge developments in the area.

International conference in memory of Prof. Ivan Todorov, encompassing modern topics at the intersection of physics and mathematics — quantum field theory, elementary particle physics, quantum symmetries, and mathematical physics. Organised by INRNE-BAS, ICMS-Sofia and IMI-BAS.

The Workshop on Computational Neuroscience aims at gathering scientists from various fields of computational neuroscience, including multi-modal brain data acquisition, data analysis and modeling of brain activity. The main goal of the event is to share experience of world leading scientists with fellow scientists and with young researchers and establish new long-term collaborations among them. The workshop will include frontal lectures and a Round Table.
