Mathematical Fluid Mechanics


    theory of hyperbolic conservation laws

      •   towards a proper solution concept for the multi-dim. compressible Euler equations

      •   convex integration, non-uniqueness for the multi-dim. compressible Euler equations


    structure preserving numerical schemes for Euler and ideal magnetohydrodynamics

      •   well-balanced and low Mach schemes for Euler equations with gravity

      •   genuinely multi-dim. schemes

      •   structure-preserving compact high-order method method


    applications in astrophysics

      •   numerical schemes for evolving stellar structure and evolution

      •   simulations of the evolution of the universe including magnetic fields


    kinetic equations and plasma, theory & numerics

      •   multi-species models, existence and qualitative behavior

      •   numerical schemes for multi-species BGK equations based on a variational procedure


    PDE inverse problems, kinetic models in biology with coefficients determined by experimental data

      •   theory: proving that it is possible to solve certain kinetic PDE inverse problems

      •   numerics: schemes that determine the coefficients from given experimental data
