SUMMARY:Семинар на секция ИОВС и Семинар по оптимизации на ФМИ - СУ
DESCRIPTION:На 1 юни 2026 г. (понеделник) от 14:15 часа в зала 503 на ИМИ-БАН\nще се проведе съвместно заседание на Семинара по изследване на операциите на ИМИ-БАН\nи Семинара по оптимизация на ФМИ при СУ “Св. Климент Охридски”. \nДоклад на тема \nOn the subregularity of mappings associated to optimization problems\nще изнесе 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. \nЗа желаещите да участват дистанционно е предоставена връзка за Zoom-сесията:\nhttps://us02web.zoom.us/j/82844903143?pwd=iX70nEcAaqDm9sMqMNYGtDY5zS7F2r.1 \n  \nПоканват се всички\, които се интересуват от темата.

SUMMARY:Поредица от лекции по теория на представянията и математическа физика - Иван Димитров\, лекция 3
DESCRIPTION:ICMS Distinguished Lecture series in Representation Theory and Mathematical Physics\nДата и място: \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 \nЛектор: \nIvan Dimitrov (Queen’s University\, Canada) \nТема:\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/

SUMMARY:Съвместен семинар на МЦМН и секция АГТ
DESCRIPTION:Date and time: Tuesday\, June 2-nd\, 2026\, 13:00\, room 403 IMI-BAS \nLecturer: Bogdan Djordjevic\, (Serbian Academy of Arts and Sciences\, visitor at ICMS\, IMI-BAS) \nTitle: Application of the Laplace transform for evaluating sums of hyperharmonic-like series in Banach algebras and modules \nAbstract: In this talk it will be shown how the Laplace transform (in respective Banach spaces) can be utilized for evaluating sums of Banach-space-valued series. We demonstrate the technique on various abstract generalizations of the numerical hyperharmonic series\, including noncommutative setting and non-invertible setting. As an application\, we obtain new necessary consistency condition for the Sylvester equation \(\)ax-xb=c[\latex].
