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)

Spatial structures appear throughout mathematics, connecting topology, combinatorics, and geometry in surprising and beautiful ways, capturing how mathematical objects sit and interact within the spaces around them. This workshop aims to bring together researchers from a range of backgrounds to strengthen the community and to discuss developments in the theory of spatial structures, with a particular focus on topological graph theory, spatial graphs, braids, and periodic tillings.

The topic of the workshop is traditionally very broad with many different areas ranging from elliptic and parabolic equations, singular analysis, geometric aspects of PDEs, and applications.

The topics of interest of this conference include results and applications in: function approximation; integral and differential operators; linear and nonlinear approximation; numerical analysis; computational methods for differential equations; inverse problems; data-driven numerical methods; numerical filtering algorithms; probability and statistics; statistical computation; stochastic analysis; SDEs; SPDEs; numerical methods for stochastic problems; stochastic optimization, statistical inference for stochastic models. The conference will be held in a hybrid format.

ICINSA-2026: The International Conference on “Innovation in Nonlinear Science and Its Applications” aims to bring together researchers, academicians, scientists, industry professionals, and students from across the globe to discuss recent advances, emerging trends, and innovative applications in the broad field of nonlinear science.

This Arbeitsgemeinschaft will study localization and delocalization phenomena for discrete random Schrödinger operators and related random matrix and graph models. Our emphasis will be on: • spectral-theoretic criteria for localization (RAGE, spectral types, Green function criteria), • the fractional moment method and high-disorder localization, • random band matrices (localization vs delocalization transition), • multiscale analysis for lattice models, especially Bernoulli distributions, • discrete unique continuation and its role in modern Bernoulli localization proofs, • absolutely continuous spectrum and resonant delocalization on regular trees • random graphs (Erdős–Rényi). As in typical AG format, not all items may be covered; the final selection may depend on participant interest and background. Deadline for application: 1 July 2026

The seminar focuses on Hilbert’s irreducibility theorem and its modern reinterpretations as an arithmetic-geometric property of varieties over number fields. Originating in Hilbert’s work on realizing finite groups as Galois groups, these ideas have since evolved through contributions by Colliot-Thélène, Sansuc, Serre, Corvaja, Zannier and others into the study of the so-called Hilbert and weak Hilbert properties, which describe the abundance and distribution of rational points on varieties and their behavior under covers. In recent years, the subject has seen remarkable progress, with new results on algebraic groups, abelian varieties, del Pezzo surfaces, and K3 surfaces. The aim of this seminar is to introduce PhD students and postdocs to these developments and to the techniques used in their proofs. Deadline for application: 12 July 2026

There is an increase of models in fluid dynamics which incorporate new stochastic and relaxation effects. For the stochastic part, this focuses on the well-posedness of PDEs with rough boundary noise. Relaxation effects lead to new models avoiding infinite propagation speed, but also questions global well-posedness known for classical models. The development and analysis of numerical schemes has also been extensively investigated. The seminar aims at reporting on these recent developments, and at discussions among an up-and-coming community. Deadline for application: 12 July 2026
