Multi-symplectic Runge-Kutta-type methods for Hamiltonian wave equations. (English) Zbl 1100.65117
The nonlinear wave equation is taken as a model problem for the investigation. Different multi-symplectic reformulations of the equation are discussed. Multi-symplectic Runge-Kutta methods and multi-symplectic partitioned Runge-Kutta methods are explored based on these different reformulations. Some popular and efficient multi-symplectic schemes are collected and constructed. Stability analyses are performed for these schemes.
