Prof. Avi Wigderson is a world-leading mathematician and computer scientist specializing in algorithms and complexity theory. His fundamental contributions have been recognized with the highest awards, including the Abel Prize (widely considered the “Nobel Prize of Mathematics”) and the Turing Award (the highest distinction in computer science, often referred to as the “Nobel Prize of Computing”). In this talk, he will discuss expander graphs, their constructions, and their applications.

The talk with start at 4pm (UK time). At the scheduled time, join the talk here.

This workshop, sponsored by AIM and the NSF, will be devoted to combinatorial coding theory, a field of mathematics that applies discrete structures and algorithms to solve problems in communications. Examples of seminal results in this field include Shannon's noisy channel coding theorem, asymptotically good codes from expander graphs, and capacity achieving spatially-coupled low-density parity-check (LDPC) codes and iterative decoding algorithms. This workshop will aim to build new collaborations in combinatorial coding theory, provide a welcoming environment for new researchers to join the community, develop and strengthen the community of researchers in coding theory, provide mentoring experience to junior faculty, and ignite new lines of research for researchers at all stages.

The main topics for the workshop are

Graph-based codes Quantum error-correction Coding for storage, such as storage in DNA, private information retrieval (PIR), convertible codes, and codes with locality This event will be run as an AIM-style workshop. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and parallel working sessions.

Space and funding is available for a few more participants. If you would like to participate, please apply by filling out the on-line form no later than November 13, 2025.

This workshop, sponsored by AIM and the NSF, will be devoted to drawing connections in between integrable probability, quantum groups and Hecke algebra, and combinatorics. Recent developments have shown exciting and potentially innovative bridges between these historically distinct fields.

Specific topics discussed during the workshop will include:

1. Integrable probability, especially asymptotics, such as Tracy-Widom fluctuations, large deviations, and stationary measures.
2. Algebraic structures with the Yang-Baxter Equation, specifically Hecke algebras and quantum groups, and their relationship to asymptotics.
3. Combinatorial constructions of the aforementioned algebraic objects, and combinatorial formulas for probabilistic expressions.

The 22nd International Conference on Fibonacci Numbers and Their Applications will be held at Galatasaray University, Istanbul, on July 6–10, 2026. The conference aims to bring together researchers from all areas of mathematics and science with interests in recurrence sequences, their applications and generalizations, and other special number sequences.

The Annual International Conference of the Georgian Mathematical Union was established in 2010 and has been held traditionally at Batumi Shota Rustaveli State University. Batumi is the city of Georgia and the capital of the Autonomous Republic of Adjara. It is located along the coast of the Black Sea in the southwest region of Georgia. In accordance with recent developments, the conference has been conducted in a hybrid format since 2021. The purpose of the conference is to bring together mathematicians from various fields to present their original research results and provide opportunities to establish new connections within the fields of pure and applied mathematics, as well as science, engineering, and technology. The conference also provides valuable networking opportunities for you to meet great personnel in these fields.

The conference sections: Algebra and Number Theory; Differential and Integral Equations, and Their Applications; Geometry and Topology; Logic, Language, Artificial Intelligence; Mathematical Education and History of Mathematics; Mathematical Logic and Discrete Mathematics; Mathematical Modeling and Numerical Analysis; Theoretical Physics; Probability Theory and Statistics, Financial Mathematics; Real and Complex Analysis.

Please share this opportunity with potentially interested students and postdocs.

The application deadline for the Heidelberg Laureate Forum (HLF) 2026 is Feb 11, 2026. See https://www.heidelberg-laureate-forum.org/ for details.

The HLF offers a rare opportunity for students, PhD candidates, and postdocs in mathematics and computer science to spend a week interacting with Abel Prize, Fields Medal, Turing Prize, ACM Prize in Computing, IMU Abacus Medal and Nevanlinna Prize laureates, as well as with other outstanding international early-career mathematicians and computer scientists from around the world, and a variety of distinguished guests. The program includes lectures, workshops, panel discussions, networking events, and more. All local expenses (hotel and meals) are covered and an option to apply for travel funding exists if needed.

Participating in an HLF is a wonderful opportunity in many ways.
