OnOn August 7, 2025, the Conference Celebrating the Consortium IMSAC was officially opened at the Institute of Mathematics and Informatics (IMI–BAS) in Sofia. The event honors the long-standing collaboration among leading mathematical institutes across the USA, Latin America, Asia, and Europe, united in the Institute of the Mathematical Sciences of the Americas Consortium (IMSAC).

At the opening, Prof. Julian Revalski, Director of the International Center for Mathematical Sciences – Sofia (ICMS-Sofia), greeted the participants and emphasized the importance of international cooperation in advancing contemporary mathematics. Prof. Peter Boyvalenkov, Director of IMI-BAS, welcomed the guests to the institute and wished them a fruitful and inspiring conference.

The opening of the conference also sets the tone for a vibrant month of mathematical activity inBulgaria and coincides with an important milestone — the end of the first year of the activities of the research group Theory of Atoms, led by Prof. Ludmil Katzarkov.

Established under the auspices of ICMS-Sofia at the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences, the Theory of Atoms group has quickly become a dynamic center for high-quality mathematical research. Its members explore deep connections between modern geometry, category theory, and mathematical physics, including areas such as homological mirror symmetry, Fukaya categories, categorical dynamics, and symplectic geometry.

To celebrate this milestone and showcase ongoing developments in the group’s core areas, ICMS-Sofia and IMSA are organizing two more high-profile events throughout August 2025:

  • Conference Geometry at Large, August 11–14, 2025, Burgas. The event will focus onrecent developments in geometry, with strong thematic links to the Theory of Atoms program.
  • Workshop New Developments on Arnold’s Conjecture, August 16–17, 2025, Sofia, dedicated to recent results and innovative approaches to Arnold’s conjecture. This workshop continues the group’s tradition of engaging with deep problems in symplectic topology.

These events not only celebrate a year of creativity and collaboration, but also mark the beginning of a new chapter in the journey of the Theory of Atoms, which is set to continue pushing the boundaries of modern mathematics.
