Projected Variational Integrators for Degenerate Lagrangian Systems
Michael Kraus
We propose and compare several projection methods applied to variational integrators for degenerate Lagrangian systems, whose Lagrangian is of the form $L = \vartheta(q) \cdot \dot…

Metriplectic Integrators for the Landau Collision Operator
Michael Kraus, Eero Hirvijoki
We present a novel framework for addressing the nonlinear Landau collision integral in terms of finite element and other subspace projection methods. We employ the underlying metri…

Variational Integrators for Ideal Magnetohydrodynamics
Michael Kraus, Omar Maj
A variational integrator for ideal magnetohydrodynamics is derived by applying a discrete action principle to a formal Lagrangian. Discrete exterior calculus is used for the discre…
