We are pleased to announce the conference Geometry at Large, which will take place at the Instituto de Ciencias Matemáticas (ICMAT), in Madrid (Spain), during 21-25 April 2025. This event, organized jointly by ICMAT and the Institute of the Mathematical Sciences of the Americas (IMSA), aims to bring together leading researchers from Spain and Latin America to explore a wide range of topics within the broad field of geometry, including algebraic geometry, differential geometry, geometric group theory, etc. It will provide a platform for presenting the latest advancements in these areas, and for fostering scientific collaboration between the mathematical communities of Spain and Latin America. Every person interested in participating in the conference must pre-register here before 20 January 2025. Confirmed participants will receive an email from the organizing committee no later than 31 January 2025. There may be limited funds to cover the accommodation of a small number of young researchers. Interested people should tick the appropriate box on the pre-registration form. All the details about the conference may be found at the conference website. The organizers, Javier Aramayona (ICMAT), Oscar García-Prada (ICMAT), Ludmil Katzarkov (IMSA), Jaqueline Mesquita (Brasilia)

The 3rd International Mathematics and Statistics Student Research Symposium (IMSSRS) will be held virtually on Saturday, April 12, 2025. IMSSRS is a free conference welcoming high school, community college, undergraduate, and graduate students to present their mathematics and statistics research, explore current research topics, and connect with like-minded enthusiasts. This year’s program features a keynote address by Dr. Susan Goldstine (St. Mary’s College of Maryland) on "The Long and Winding Road to Non-Euclidean Geometry." There will also be a panel discussion on "Life After College," exploring career options for mathematical science graduates, with opportunities for audience Q&A. Abstract submission and registration deadlines are March 28. While presenters must be students, all are welcome to attend. Visit the event website for more details and share the experience with fellow students and colleagues.

The geometric arrangement of a material’s constituents plays an important role in governing its behavior. Concepts from discrete mathematics to describe these geometric arrangements, including notions of rigidity and flexibility, can bring fundamental insight into how a material might respond to stress, be designed, be reconfigured, etc. Beyond materials, the notions of network rigidity can be applied to more abstract networks and geometries, such as those found in data science. This workshop aims to build connections between the field of mathematical rigidity theory, other topics in applied mathematics, and related areas of science and engineering.

The workshop will explore various topics related to discrete structures and randomness, including but not limited to percolation, random graphs, and stochastic geometry. The program will feature presentations from the 9 keynote speakers below, as well as contributed talks. - Timothy Budd (Radboud University) - Nicolas Curien (Université Paris-Sud) - Daniel Dadush (Utrecht University) - Zakhar Kabluchko (University of Münster) - Júlia Komjáthy (Delft University of Technology) - Irène Marcovici (Université de Rouen Normandie) - Giovanni Peccati (University of Luxembourg) - Wioletta Ruszel (Utrecht University) - Clara Stegehuis (Twente University) For more information and registration, please visit our website: https://sites.google.com/rug.nl/words2025/home The registration deadline is February 28, 2025. We encourage junior researchers to propose a contributed talk. We look forward to seeing you in Groningen! Tobias Müller, Réka Szabó and Gilles Bonnet

The goal of this conference is to present a panorama of research directions in mathematics and mathematical physics related to the scientific program of our CRC 1624 "Higher structures, moduli spaces and integrability". The CRC 1624 has started in the Spring of 2024. It aims to stimulate interactions between highly active topics in mathematics such as higher structures and their applications in TQFT and CFT, the geometry of moduli spaces with their applications in SUSY QFT and string theory like the swampland program, and integrability with its multitude of applications in quantum field theory and string theory. With this conference we aim to stimulate new interactions between mathematics and theoretical physics by bringing together leading representatives of these research directions.

This is an informal workshop entirely dedicated to young mathematicians who work in differential geometry in a broad sense. The scientific theme of the workshop is the study of topological and geometric properties of complex manifolds, and, more in general, of manifolds endowed with ''special'' geometric structures, either integrable or non-integrable.

The Hanseatic Dynamical Systems Days (HanDSDays) are recurring one-day workshops taking place at universities in Northern Germany. The goal of the workshop is to enhance connections, collaborations and exchange of ideas within the Dynamical Systems & Ergodic Theory community. The 11th HanDSDay will take place at the University of Bremen at March 28th, 2025. For more information: https://sites.google.com/view/handsdays11

The S.-T. Yau College Student Mathematics Contest, initiated by Prof. Shing-Tung Yau in 2010, reaches its 16th edition in 2025 with the first global expansion. Hosted by Tsinghua University’s Yau Mathematical Sciences Center, this competition has attracted over 25,000 participants from 600+ universities in China with 980+ awardees honored. In 2025, the competition expands internationally, setting up test centers in the USA (California-Los Angeles, Berkeley; New Jersey-New Brunswick; Massachusetts-Boston; Texas-Houston), Russia (Moscow, Saint Petersburg), Japan (Tokyo), and Singapore. It is open to undergraduate students worldwide who have not yet obtained a bachelor’s degree. Registration runs from March 15 to April 15, 2025. The semifinal written examination will take place on May 17–18, 2025. The global finals will be held at Tsinghua University in Beijing from June 28–29.

This workshop will be centered on recent advances in graph rigidity and interactions between rigidity, algebraic statistics, and matroid theory. Three major advances are the recent resolution of the matroid maximality conjecture, the newly developed link to maximum likelihood estimation in Gaussian graphical models, and the recent positive resolution of Lovasz and Yemini's connectivity conjecture for generic rigidity. The workshop will showcase a diverse sample of current work addressing fundamental problems in graph rigidity, algebraic matroids, and algebraic statistics.

Control theory and reinforcement learning converge on a shared objective: facilitating autonomous, real-time decision-making to optimize dynamical processes. Historically, these disciplines have diverged in assumptions regarding available prior information and in analytical techniques applied. However, recent advances bridging the two domains are fostering collaborations. The upcoming CWI research semester programme in spring 2025, themed "Control Theory and Reinforcement Learning: Connections and Challenges", will comprise a spring school and workshops on various sub-topics, orchestrated by a distinguished team including Aditya Gilra, Bert Kappen, Debabrota Basu, Frans Oliehoek, Maryam Kamgarpour and Sean Meyn, to explore the intersections and challenges within these intertwined fields.
