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

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

Dynamo theory studies the spontaneous growth of magnetic fields in electrically conducting fluids and is a fundamental branch of magnetohydrodynamics, with important applications in planetary physics and astrophysics. Magnetic relaxation is in a sense the counterpart of dynamo action: a magnetic field seeks a minimum energy state compatible with its topology – a driving mechanism in the dynamics of the solar corona and in fusion plasmas. Both theories provide insight into fundamental questions of classical hydrodynamics. For instance, magnetic evolution is closely analogous to vorticity evolution under ideal (Euler) dynamics and magnetic relaxation is a way to generate steady Euler flows with prescribed topology. There is a large body of well-established theory in these questions but significant mathematical challenges remain. The low-viscosity/low-resistivity regime relevant to most MHD flows is characterized by the emergence of small scales, with an interplay between stretching of magnetic streamlines and magnetic diffusion. The description of these small scales and their averaged effect on MHD instabilities or relaxation phenomena is a major issue. The seminar will focus on recent mathematical developments in this area through lectures, discussions and some brief presentations. Deadline for applications: 6 September 2026

Evolutionary PDEs play a crucial role in the description of countless physical processes. The numerical treatment of these time-dependent problems is challenged by plenty of difficulties such as, the propagation of singularities, the preservation of structural properties, oscillatory and multi-scale behaviour as well as the high-dimensionality of the variables involved. This seminar focuses on dynamical parametric approaches to approximate the solution of certain classes of PDEs at time t. The seminar will consist of a series of roughly ten lectures and accompanying group work. We plan to address the following topics: (1) time-dependent variational principle, (2) approximation properties of decoder functions, (3) time integration, (4) practical aspects, e.g., optimization, sampling, and automatic differentiation.
