IMI-BAS Launches the Atanasoff Memorial Lecture Series Celebrating John Vincent Atanasoff
On November 10, 2025, the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences will host the Atanasoff Memorial Day event - a new initiative of the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences and the International Center for Mathematical Sciences (ICMS-Sofia) at the IMI-BAS. The organizers' ambition is to hold the Atanasoff Memorial Lecture Series program every year, thus commemorating the memory of John Vincent Atanasoff (1903–1995) - a computer pioneer, inventor of a model of an electronic digital computer and renowned as the "Bulgarian father of the electronic computer". It aims to celebrate the intersection of mathematics, computation, and the sciences of complexity — the very domains that unite topology, geometry, and machine learning in the 21st century.
THE ALGEBRA OF AVALANCHES – Public Lecture by Ernesto Lupercio — Ramanujan Prize Laureate
On November 10, 2025, at 10:00 a.m. in Room 403 of IMI–BAS, Professor Ernesto Lupercio will deliver a public lecture titled “The Algebra of Avalanches: From Sandpiles to the Hidden Symmetries of the Universe.” Professor Lupercio, chair of the research group “Topological, Computational, and Algebraic Aspects of Complex Systems” at ICMS–Sofia, is an internationally recognized mathematician and recipient of the ICTP Ramanujan Prize and the Marcos Moshinsky Research Award.
A Year of Collaboration and Discovery in the Theory of Atoms Group
On August 7, 2025, the Conference Celebrating the Consortium IMSAC was officially opened at the Institute of Mathematics and Informatics (IMI–BAS) in Sofia. The event honors the long-standing collaboration among leading mathematical institutes across the USA, Latin America, Asia, and Europe, united in the Institute of the Mathematical Sciences of the Americas Consortium (IMSAC). At the opening, Prof. Julian Revalski, Director of the International Center for Mathematical Sciences – Sofia (ICMS-Sofia), greeted the participants and emphasized the importance of international cooperation in advancing contemporary mathematics. Prof. Peter Boyvalenkov, Director of IMI-BAS, welcomed the guests to the institute and wished them a fruitful and inspiring conference. The opening of the conference also sets the tone for a vibrant month of mathematical activity inBulgaria and coincides with an important milestone — the end of the first year of the activities of the research group Theory of Atoms, led by Prof. Ludmil Katzarkov.
The International Conference Celebrating the Consortium IMSAC brings together mathematicians from four continents
From August 7 to 9, 2025, the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences (IMI–BAS) will host the International Conference Celebrating the Consortium IMSAC - an event that brings together distinguished mathematicians from around the world. The conference is jointly organized by the International Center for Mathematical Sciences – Sofia (ICMS-Sofia) at IMI–BAS and the Institute for the Mathematical Sciences of the Americas (IMSA) at the University of Miami. The Celebrating the Consortium IMSAC conference will take place in Hall 403 at the Institute of Mathematics and Informatics in Sofia. The programme starts with a talk by the Fields Medalist Caucher Birkar. Over the course of three days, leading researchers from the IMSAC network will present their latest results, discuss joint projects, and explore new directions in mathematics and its applications.
