First International Conference “Responsible Creation of Artificial General Intelligence”

Университетски център „Бачиново“ - Благоевград 42°01'59.6"N 23°07'46.6"E, Благоевград

The Institute of Mathematics and Informatics is pleased to announce RC-AGI 2026. This is an international conference jointly organized by our institute and the South-West University “Neofit Rilski”. Conference objectives: Mankind is on the verge of its most important discovery, one that will fundamentally change our life and future. The creation of AGI is similar to letting the genie out of the bottle. In fairy tales there is usually only one bottle and the question is whether to open it or not. With AGI the opening the bottle is inevitable because many researchers and international companies are working on its creation and no one can stop or prohibit them from creating it. Furthermore, when we are about to let the AGI genie out of [...]

National Seminar on Probability and Statistics

Institute of Mathematics and Informatics, BAS Akad.G.Bonchev St, bl. 8, 1113, Sofia

The next meeting of the National Seminar on Probability and Statistics will be held on May 20, 2026, at 2:00 p.m. in Room 503 of the Institute of Mathematics and Informatics. A talk on: Finite time blowup and existence of global solutions of a semi-linear stochastic partial differential equation with fractional noise will be delivered by Ekaterina Todorova Kolkovska (Center for Research in Mathematics Guanajuato, Mexico). Abstract: We consider a stochastic partial differential equation driven by fractional Brownian motion with Hurst parameter H greater or equal to 1/2 on a bounded domain with smooth boundary and Dirichlet boundary conditions. By means of an associated random partial differential equation, lower and upper bounds for the blowup time of the solution are given. Sufficient conditions for [...]

ICMS Distinguished Lecture series in Representation Theory and Mathematical Physics – Ivan Dimitrov, Lecture 2

Institute of Mathematics and Informatics, BAS Akad.G.Bonchev St, bl. 8, 1113, Sofia

ICMS Distinguished Lecture series in Representation Theory and Mathematical Physics Date and place: May 19 and 21, 2026 (15:00–16:00 Sofia time) and June 1, 3 and 5, 2026 (16:00–17:00 Sofia time), Room 403, IMI - BAS Lecturer: Ivan Dimitrov (Queen’s University, Canada) Title: Root systems, generalizations and applications Root systems were introduced by Wilhelm Killing in 1889 as a tool for classifying Lie algebras. Since then, they have become ubiquitous, appearing in various contexts in seemingly unrelated areas of Mathematics. In this lecture series, Ivan Dimitrov introduces and studies root systems and defines a generalization of root systems. He explains how this more general structure applies to various problems, e.g. hyperplane arrangements. Finally, he introduces and studies inversion sets of roots. The exposition is [...]

International Conference on Mathematical Quantum Field Theory

Bulgarian Academy of Sciences 1, 15th November Str., Sofia, Sofia City

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 [...]
