SUMMARY:International Conference on Mathematical Quantum Field Theory
DESCRIPTION:Mathematical Quantum Field Theory\n\n\n\nInternational conference in memory of Ivan Todorov\n\n\nStart date: 26 May 2026\nEnd date: 30 May 2026\nEvent location: Hall “Prof. Marin Drinov”\, BAS\, Sofia\, Bulgaria \n\n\nOrganized 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 \nThe 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. \nIvan 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 career at the Institute for Nuclear Research and Nuclear Energy (INRNE-BAS) and held many fruitful collaborations with colleagues around the world. This conference brings together former students\, collaborators\, and friends to celebrate his scientific legacy and international recognition. \nRead more on https://indico.global/event/16645/overview

SUMMARY:Digital Culture Seminar
DESCRIPTION:The next meeting of the Digital Culture Seminar \nwill be held on May 26\, 2026 (Tuesday) at 10:00 a.m. in Room 278 of IMI – BAS. \nA talk on: \nLogics for Strategic Reasoning about Socially Interacting Rational Agents\nwill be delivered by Valentin Goranko\, Stockholm University\, Sweden. \nAbstract: An important aspect of socially interacting rational agents are the strategic abilities of individual agents and groups (coalitions) of agents to guarantee the achievement of their desired goals\, while acting and interacting within an entire society of agents. Several logical systems have been proposed for formalising and capturing such reasoning were introduced the early 2000s\, starting with the Coalition Logic (CL)\, the Alternating Time Temporal Logic (ATL)\, and some extensions of these. \nCoalition Logic provides a natural\, but rather restricted perspective: the agents in the proponent coalition are viewed as acting in full cooperation with each other but in complete opposition to all agents outside of the coalition\, which are thus treated as adversaries. The Alternating Time Temporal Logic extends Coalition Logic with temporal operators allowing for expressing long-term temporised goals. \nThe strategic interaction in real societies is much more complex\, usually involving various patterns combining cooperation and competition. To capture these\, more expressive and versatile logical frameworks are needed. \nIn this talk I will give a brief overview of some of these logics and will illustrate their use with some examples. \nZoom link:\nhttps://us06web.zoom.us/j/82219689652?pwd=VbWffI8RD4aPYC8TaNrasukEW7uePV.1

SUMMARY:Seminar in Operations Research\, Probability and Statistics of IMI-BAS and Optimization Seminar of FMI-SU
DESCRIPTION:On June 1st\, 2026 (Monday) at 2:15 pm in room 503 of IMI-BAS\na joint meeting will be held of the Operations Research\, Probability and Statistics Seminar of IMI-BAS\nand the Optimization Seminar of the Faculty of Mathematics and Informatics\, Sofia University. \nA talk on: \nOn the subregularity of mappings associated to optimization problems\nwill be delivered by Alberto Dominguez Corella\, University of Graz\, Austria. \nAbstract: This talk is meant as a nontechnical discussion on the concept of metric subregularity and its application to the study of stability in optimization problems. It features equivalences between the property and local error bounds\, as well as theoretical applications\, e.g.\, discretization\, approximation\, and differentiation with respect to parameters. We describe several concrete applications\, including inverse problems and optimal control. The talk will be based on several joint works with Nicolai Jork\, Vladimir Veliov\, Trı Minh Le and Eduardo Casas. \nZoom link:\nhttps://us02web.zoom.us/j/82844903143?pwd=iX70nEcAaqDm9sMqMNYGtDY5zS7F2r.1\n  \nEveryone interested in the topic is cordially invited to participate.

SUMMARY:ICMS Distinguished Lecture Series in Representation Theory and Mathematical Physics - Ivan Dimitrov\, Lecture 3
DESCRIPTION:ICMS Distinguished Lecture series in Representation Theory and Mathematical Physics\nDate and place: \nMay 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 \nLecturer: \nIvan Dimitrov (Queen’s University\, Canada) \nTitle:\n \nRoot systems\, generalizations and applications\nRoot 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 mostly self-contained\, assuming Linear algebra and some Group theory background. \nhttps://icms.bg/event/root-systems-ivan-dimitrov-lecture-series/
