The 17th International Workshop on Well-Posedness of Optimization Problems and Related Topics will take place between 13-17 July 2026 in hotel “Samokov”, Borovets, Bulgaria. The workshop is organized by the Faculty of Mathematics and Informatics at Sofia University “St. Kliment Ohridski” and the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences, and is dedicated to the 70th anniversary of Julian Revalski.

Organizers:

• Mikhail I. Krastanov (IMI-BAS & Sofia University “St. Kliment Ohridski”)
• Nadezhda K. Ribarska (Sofia University “St. Kliment Ohridski” & IMI-BAS)
• Nadia P. Zlateva (Sofia University “St. Kliment Ohridski”)

A traditional conference celebrating the collaboration between many institutes in USA, Latin America, Asia and Europe included in the Institute of the Mathematical Sciences of the Americas Consortium (IMSAC). The event is jointly organised by the International Centre for Mathematical Sciences (ICMS‑Sofia) at the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, and the Institute for the Mathematical Sciences of the Americas (IMSA) at the University of Miami.

The conference brings together leading senior researchers and promising early-career scholars working in the field of Geometry to popularise recent developments and new achievements. It also seeks to give young scholars from South-Eastern Europe the opportunity to engage with cutting-edge research and meet leading experts from around the world.

The aim of this conference is to bring together researchers to share recent advances, promote further developments in the theory of Quantum Groups and Cluster Algebras, and to investigate their interactions and applications across mathematics and physics. Quantum groups and cluster algebras both provide frameworks for encoding algebraic and geometric structures arising in representation theory, geometry, and mathematical physics. Quantum groups, as deformations of universal enveloping algebras, capture generalized symmetries with rich categorical and representation-theoretic properties. On the other hand, Cluster algebras, introduced by Fomin and Zelevinsky, appear as important algebraic varieties and reveal properties of them through combinatorial rules. Cluster algebras are essential in the study of canonical bases in diverse settings.

• Milen Yakimov (ICMS – Sofia & Northeastern University)
• Emine Yıldırım (ICMS – Sofia)
