### From linear to nonlinear model order reduction: some results and perspectives – Giovanni Stabile (Università di Urbino)

Non-affine parametric dependencies, nonlinearities, and advection-dominated regimes of the model of interest can result in a slow Kolmogorov n-width decay,…

### The J-invariant of linear algebraic groups of outer type – Nikita Geldhauser (LMU Munich)

The J-invariant is a discrete invariant of semisimplealgebraic groups which describes the motivic behavior of the variety ofBorel subgroups. This invariant was an important tool to solve severallong-standing problems. For example, it plays an…
