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/
