The International Center for Mathematical Sciences – Sofia (ICMS-Sofia) hosts an international conference on Quantum Groups and Cluster Algebras between 15-19 December 2025 at the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, with the financial support of the Simons Foundation, Republic of Bulgaria - Ministry of Education and Science and Institute of Mathematics and Informatics, and Bulgarian Academy of Sciences. The aim of this conference is to bring together researchers to share recent advances and promote further developments in the theory of Quantum Groups and Cluster Algebras.

Tropical sandpiles stand at the crossroads of mathematics, computer science, machine learning, algebra, physics, and mathematical logic. Originating from models of self-organized criticality, they reveal intricate combinatorial and geometric structures that echo through algebraic geometry and tropical mathematics. Their dynamics connect to complexity theory and algorithmic design in computer science, while also inspiring methods in statistical mechanics and the study of complex systems in physics. More recently, tropical sandpile models have begun to interact with approaches in data science and machine learning. At the same time, their formal underpinnings invite connections to logic and the foundations of computation — providing a common language where diverse disciplines converge.

The research group “Theory of Atoms”'s Leonardo Kavenaghi will give series of lectures
The Theory of Atoms is a recent formalism introduced by Katzarkov, Kontsevich, Pantev, and Yu, which aims to integrate classical Hodge theory with symplectic geometry, seeking applications in birational geometry.
To properly understand it, we must gather concepts from many areas of knowledge, ranging from Gromov-Witten theory and enumerative algebraic geometry to classical and noncommutative Hodge theory. This series is designed to be an example-driven introduction, providing the essential background needed to understand this new theory.

The research group “Theory of Atoms” will give two talks that will highlight recent advances.
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.
Friezes, originally introduced by Coxeter, are simple objects which however turned out to be connected with surprisingly many seemingly unrelated concepts from a variety of subjects. These include combinatorics (polygon dissections), number theory (continued fractions), geometry (the Farey graph), and algebra (cluster algebras -- a hot topic of their own). I will survey these connections using interactive visualisations, introduce the family of basic examples of cluster algebras, and present a new connection between not-necessarily-positive friezes and cluster algebras.
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.
