IMI-BAS Launches the Atanasoff Memorial Lecture Series Celebrating John Vincent Atanasoff

2025-11-06T17:19:49+02:00November 6th, 2025|News|

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.

2025-10-31T18:32:29+02:00August 8th, 2025|News, Theory of Atoms|

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

2025-08-06T12:24:12+03:00August 6th, 2025|News|

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.

International Conference “Singularities in Plovdiv”

2025-05-28T16:47:24+03:00April 29th, 2025|Conferences, News|

The goal of the conference is to bring together world-renowned and early-career researchers working in the field of algebraic geometry, low-dimensional topology, complex geometry and commutative algebra and foster discussions around singularities in topology, metric geometry, algebraic geometry, dynamical systems and mirror symmetry. The meeting also seeks to provide an opportunity for young scholars from Eastern Europe to engage with cutting edge research in the area.

On Motivic and Arithmetic Donaldson-Thomas invariants, ICMS seminar talk by Felipe Espreafico Guelerman

2025-04-23T12:31:07+03:00April 1st, 2025|ICMS Seminar, News|

Aiming to understand the relation to other "refined invariants", and especially their possible interpretation in quantum theory, we explain how to obtain a quadratic, A1-version of Donaldson-Thomas invariants from the motivic refinements first introduced in Kontsevich-Soibelman. Following ideas from Behrend, Bryan and Szendroi, we provide predictions for these invariants in a few simple examples, mainly the computation of DT invariants of A3. Our main goal is to draw relationships with the literature, including works of Levine, Denef and Loser, Azouri, Pepin-Lehaulleur, Srinivas among others. We begin with a brief introduction to A1-enumerative geometry and in the end, we pose some further questions on possible extensions of our definitions. This is joint work with Johannes Walcher. We also comment on joint work in progress with Ran Azouri.

Complex structures on Lie algebras and its application to the Hull-Strominger system, ICMS seminar talk by Luis Ugarte

2025-03-25T18:49:33+02:00March 25th, 2025|ICMS Seminar, News|

In this talk we will explain the role that the Lie algebras play in the construction of 6-dimensional compact quotient spaces M=G/Γ, where Γ is a lattice, endowed with an invariant complex structure with holomorphically trivial canonical bundle.
