Mathematical Quantum Field Theory International conference in memory of Ivan Todorov Start date: 26 May 2026 End date: 30 May 2026 Event location: Hall “Prof. Marin Drinov”, BAS, Sofia, Bulgaria Organized by the Institute for Nuclear Research and Nuclear Energy (INRNE) and the International Center for Mathematical Sciences at the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences The conference encompasses a wide range of modern topics at the intersection of physics and mathematics, including conformal field theory, vertex operator algebras, integrable systems, supersymmetry, gauge theory, gravity, cosmology, quantum information, and the mathematical structures that connect them. Ivan Todorov (1933-2024) was a leading Bulgarian theoretical physicist whose contributions to mathematical physics, conformal field theory, and the algebraic approach to quantum field theory shaped generations of researchers. He spent his [...]
