Title: Holonomy of the Obata connection on Joyce hypercomplex manifoldsThis will be a two-talk mini-series. In the first talk I will give a very gentle introduction to Brill–Noether theory for complex algebraic curves. I will start from the basic question: what kinds of functions can exist on a curve, and how many independent ones can we hope for? After introducing some necessary concepts, I will explain the classical results of Brill–Noether theory, which give a simple criterion for when such functions should exist on a “typical” curve. The emphasis will be on ideas and examples rather than technical details.
The Workshop on Computational Neuroscience aims at gathering scientists from various fields of computational neuroscience, including multi-modal brain data acquisition, data analysis and modeling of brain activity. The main goal of the event is to share experience of world leading scientists with fellow scientists and with young researchers and establish new long-term collaborations among them. The workshop will include frontal lectures and a Round Table.
The conference aims to bring together leading senior researchers and promising early‑career scholars working in elliptic and parabolic partial differential equations. Key topics include regularity theory and its applications, free boundary problems, singularity formation and qualitative properties of solutions. A particular emphasis will be placed on fostering participation from young scholars in Eastern Europe, providing them with the opportunity to engage with cutting-edge developments in the area. The inaugural edition of the conference took place in Plovdiv, Bulgaria in 2024. The upcoming Second Edition will be held from May 25 to May 29, 2026, in Arbanashki Han Hotel Complex, in Arbanasi, Veliko Tarnovo, Bulgaria.
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.
Minister of Education and Science Krasimir Valchev visited the International Center for Mathematical Sciences (ICMS-Sofia) at IMI-BAS on February 5, 2026. He reviewed the Center's development, which was founded in 2019 and is supported by the Ministry of Education and Science and Simons Foundation International. Highlights include 37 international events, funding for 48 researchers, and attracting five Fields Medalists. ICMS is a key player in the global mathematical network, collaborating with institutions like IMSA and IHÉS. Minister Valchev praised the Center's success in attracting international scientists.

With next lecture we are continuing the mini-course started in November. We shall discuss O. Viro’s method of patchworking. For that we need some staff from real algebraic curves, which will be discussed first, as much as the time permits.
