May 26 to May 30, 2026, the Bulgarian Academy of Sciences will host the international conference Mathematical Quantum Field Theory in memory of the renowned Bulgarian theoretical and mathematical physicist, Academician Ivan Todorov, who passed away on February 14, 2025.

Academician Todorov was a scholar with extraordinary achievements and worldwide recognition in the field of modern theoretical physics—particularly in particle theory, high-energy physics, and the mathematical foundations of physics. Throughout his long scientific career, he maintained numerous fruitful collaborations with prominent mathematicians and mathematical physicists from around the world.

The Mathematical Quantum Field Theory conference aims to cover a broad range of topics of broad interest to both physics and mathematics, while also bringing together close collaborators of Academician Todorov and researchers whose work has been significantly influenced by him. Among the speakers are many leading physicists and mathematicians. Academician Todorov had been serving on the advisor board of ICMS from the date it was established.

The conference is organized by the Institute for Nuclear Research and Nuclear Energy – BAS and the International Center for Mathematical Sciences – Sofia (ICMS-Sofia) at the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences with the support from Simons Foundation, Research Program Enhancing the Research Capacity in Mathematical Sciences (PIKOM), and Todorov Foundation.
