Inverse problems remain at the heart of scientific discovery and technological innovation, spanning fields as diverse as medical and satellite imaging, biology, astronomy, geophysics, environmental sciences, computer vision, energy, finance, and defence. Fundamentally, these problems involve using a mathematical or physical model "backwards" to infer a quantity of interest from the observed effects it produces. A main challenge resulting from using models "backwards" is that solutions are often not well posed, i.e., not unique or unstable with respect to small perturbations in the data. This difficulty continues to stimulate research and innovation at the interface of applied mathematics, statistics, engineering, and physics, leading to social and economic benefit through impact on science, medicine, and engineering. The aim of this conference is to bring together mathematicians, statisticians, and computer scientists working on the theoretical and numerical aspects of inverse problems, alongside engineers and physicists, tackling challenging applications. We will discuss recent developments and open challenges in theory, methodology, and computational algorithms. Joint Event: Big Data Day This year, the conference features a dedicated Big Data Session. Keynote Speakers Audrey Repetti – Heriot Watt University Serena Morigi – University of Bologna Samuli Siltanen – University of Helsinki Roland Potthast – University of Reading Julian Tachella – French National Centre for Scientific Research

1st International Recreational Mathematics Colloquium in Portuguese

The program will unite researchers from a number of areas: algebraic and complex geometry, arithmetic geometry, Hodge theory, and mathematical physics. It will bring theoretically and computationally oriented researchers together, expecting that computations will illuminate conjectures made by the theorists and that theory will enlarge the range of what can be computed. We intend to develop databases of certain types of K3 surfaces for the L-Functions and Modular Forms Database and promote the development of software for computations on K3 surfaces in Magma, SageMath, or other systems for public release.

The Institute of Mathematics of the Ministry of Science and Education of the Republic of Azerbaijan, in collaboration with Baku State University (Azerbaijan), Mirzo Ulugbek National University of Uzbekistan (Uzbekistan), Vasyl Stefanyk Carpathian National University (Ukraine) and Institute of Information Technology of the Ministry of Science and Education (Azerbaijan), will hold the 13th International Conference on Modern Problems of Mathematics and Mechanics. This conference will be an international forum for mathematicians, mechanical engineers and specialists in the field of mathematical education to present their latest research and development results in all areas of pure and applied mathematics, mechanics and their possible advanced applications in real life. The official language of the conference is English. Participation in the conference will be available both in-person and online.

AI Unlocked 2026, will bring together the brightest minds from academia, industry, and government to explore the power, promise and purpose of artificial intelligence. This two-day congress, chaired by Dr. Anjulika Salhan, a global expert in AI-driven innovation and founder of Systems Holdings, will be held at the prestigious Hyatt Regency in Birmingham. We invite you to join a dynamic community of AI pioneers shaping the future of machine learning and intelligent systems. World-class speakers from across sectors will share their research, breakthroughs, and real-world applications of AI, ranging from deep learning architectures and causal models to AI in finance, healthcare, governance, and regulation. Key themes include: • The evolving architecture of AI systems: transformers, GNNs, diffusion models • The rise of foundation models, multimodal AI, and explainability • Bridging theory and application: from generalisation and convergence to robust deployment • Policy and ethics: AI governance, regulatory frameworks, and public-private collaboration • What's next? Symbolic reasoning, AI safety, causal AI, and hybrid intelligence

The two-day workshop, divided into two main thematic blocks – Optimization in Machine Learning and Optimization with Fractional Calculus Methods – is primarily designed for PhD students and other interested participants. The sessions will be conducted by invited lecturers, who are recognized experts in these fields. Participation in the workshop is free of charge.

The aim of the meeting is to discuss recent developments, techniques and open questions in the area of abelian varieties and their moduli spaces, modular forms, number theory and combinatorics, automorphic forms.

The thematic scope of the conference includes, among others: • Optimization in Machine Learning • Applications of Fractional Calculus in Optimization Problems These areas reflect the dynamic development of modern optimization methods and their influence on applied mathematics, data science, and engineering. Conference Proceedings The proceedings of GPCO 2026 will be published in one of the following forms: • a monograph • a special issue of Optimization: A Journal of Mathematical Programming and Operations Research • a special issue of the International Journal of Applied Mathematics and Computer Science (AMCS)
