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.

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

The main topics of the winter school are stochastic differential equations, interacting particle systems with particular emphasis on the regularity properties of the solutions, their limiting behavior and numerical computation. The geographic location of the Kilpisjärvi Biological Station is unique. The target audience of the 5-day winter school are doctoral students and postdocs in probability, stochastic analysis, and mathematical physics. There are going to be 3 mini-courses by distinguished lecturers. Young researchers are welcome to contribute short talks and posters.
