The theory of windows was introduced relatively recently by both Halpern-Leistner and Ballard, Favero and Katzarkov, and is a great tool to study derived categories of algebraic varieties that appear as GIT constructions, as well as their behaviour at wall crossings as we vary the stability conditions.
The International Center for Mathematical Sciences at the Institute of Mathematics and Informatics (ICMS–Sofia) will commemorate the 90th anniversary of the birth of Prof. Sendov with a special talk by Edward Saff from Vanderbilt University, USA - "Sampling with Minimal Energy: A talk in commemoration of Bl. Sendov's 90th birth date."
February 8, 2022, marks the 90th anniversary of the birth of Blagovest Sendov. He passed away on January 19, 2020, shortly before reaching the age of 88. The Institute of Mathematics and Informatics and the ICMS will commemorate the 90th anniversary of the birth of Prof. Sendov with a talk by Edward Saff from Vanderbilt University, USA - "Sampling with Minimal Energy: A talk in commemoration of B. Sendov's 90th birth date."

The initiative Women in Mathematics of South-Eastern Europe, aiming at promoting the role of female mathematicians, started in Dec 2020, when the inaugural conference took place. A special distinguished guest of the inaugural conference was prof. Mina Teicher from the Department of Mathematics and Gonda Brain Research Center, Bar-Ilan University, Israel, Director of Emmy Noether Institute for Mathematics. Information about the first conference is available at: https://icms.bg/women-in-math-2020/.
These lectures will present a board survey of recent work on new q-series invariants of 3-manifolds labeled by Spin-C structures. While the original motivation for studying these invariants is rooted in topology, they exhibit a number of unexpected properties and connections to other areas of mathematics, e.g. turn out to be characters of logarithmic vertex algebras. The integer coefficients of these q-series invariants can be understood as the answer to a certain enumerative problem, and when q tends to special values these invariants relate to other invariants of 3-manifolds labeled by Spin and Spin-C structures.
On October 14, 2021, Ms. Angela Rodel, Executive Director of the Fulbright Bulgaria Program, and Ms. Maria Kostova, Program Officer, Bulgarian Grantees, visited the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences. They presented the work of the Bulgarian-American Fulbright Educational Exchange Commission and the opportunities it offers for scientists, researchers and PhD students. After the presentation, Ms. Rodel visited the International Center for Mathematical Sciences (ICMS), where she was hosted by the director of the Center - Prof. Oleg Mushkarov, and Prof. Lyudmil Katzarkov, scientific director of ICMS, who joined the event through zoom. Opportunities for cooperation and participation in Fulbright programs were discussed at the meeting.
We will start these series by reviewing the general framework of geometric Langlands correspondence, and state the main conjectures in the de Rham and Betti settings. We will also recall V. Lafforgue's theorem about the spectral decomposition in the classical Langlands over function fields. We will then proceed to the formulation of "restricted" Langlands correspondence, which unifies the different contexts. We will state the restricted version of the geometric Langlands conjecture, and explain its relation with the classical Langlands conjecture via the operation of categorical trace.
