High-order well-balanced finite volume schemes for geophysical flows : development and numerical comparisons
Many geophysical flows are merely perturbations of some fundamental equilibrium state. If a numerical scheme shall capture such flows efficiently, it should be able to preserve the unperturbed equilibrium state at the discrete level. In the first part of this thesis we present a class of schemes of …

Adaptive timestepping for conservation laws via adjoint error representation
We study a recent timestep adaptation technique for hyperbolic conservation laws. The core of the method is a space-time splitting of adjoint error representations for target functionals due to Süli [47] and Hartmann [29]. It provides an efficient choice of timesteps for implicit computations of …
