    Fusing Theory and Practice of Graph Algorithms

    Hot Topics Workshop

    Researchers working on graph algorithms use a broad range of different criteria for deciding what makes an algorithm efficient. While in theory the dominant benchmark is the asymptotic running time, in practice the story is more nuanced: an algorithm needs to be simple enough to be implementable, fast on graphs of bounded size, space efficient, cache-friendly, and easy to test. While many of these requirements motivate interesting algorithmic questions that are highly relevant in practice, they are often overlooked by the theory community. The goal of the workshop is to foster the exchange of ideas between researchers working on graph algorithms, which have high practical relevance. The workshop will include overview talks on the various perspectives, research talks, an open problem session, and structured time for collaboration. The topics of the workshop include fundamental data science graph algorithms (e.g., clustering, partitioning, graph embedding), graph neural networks, and modeling data using networks (e.g. approximate nearest neighbor search). Additionally, the workshop program incorporates problems and approaches necessitated by scaling graph algorithms to large datasets (e.g. parallel, distributed, dynamic and external memory models, as well as algorithm engineering).

    Winter School in Geometric Analysis

    Winter School

    The school in Geilo will be devoted to selected topics in analysis, geometry, and differential equations. Participants are invited to stay from Sunday evening March 2 to Friday March 7. The scientific program for the winter school will begin in the morning of Monday March 3. The main lecturers are: - Mike Eastwood (Adelaide, Australia): Prolongation and symmetry - Karin Melnick (Luxembourg): Rigid geometric structures and their automorphism groups - Sigmund Selberg (Bergen, Norway): The geometry of the light cone, the vector fields method, and global existence for non-linear wave equations - Francisco Torres de Lizaur (Seville, Spain): Dynamics of 2D and 3D divergence-free flows, with applications to fluid mechanics and magnetohydrodynamics In addition to these, the meeting will have regular / contributed lectures by participants.

    Spring School on Control Theory and Reinforcement Learning

    Spring School

    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.

    Matroids, Rigidity, and Algebraic Statistics

    ICERM Workshop

    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.

    Informal Geometry Workshop in Paradiso 2025

    Workshop

    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.

    Geometry of Materials

    ICERM Workshop

    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.
