Numerical results for a parallel linearly-implicit Runge-Kutta method
Zusammenfassung Numerical results for a parallel linearly--implicit Runge--Kutta method. For the parallelization of implicit Runge--Kutta methods for stiff ODE's a parallel computation of the stages is obvious.

Convolution-Based Chebyshev Acceleration Of Waveform Relaxation Methods
. Waveform relaxation is a numericalmethod for solving large-scale systems of ordinary differential equations. In this paper, it is investigated whether the convergence of waveform relaxation can be accelerated by Chebyshev acceleration techniques.

Symplectic Runge-Kutta Schemes III: Canonical Elementary Differentials
. It has been shown that numerical methods for Hamiltonian systems may be characterised in terms of so-called canonical elementary differentials. Recent results by the authors demonstrate that the symplecticity condition for Runge-Kutta schemes may be ...

Application of Sparse Matrix Techniques in the Chemical Part of a Large Air Pollution Model
Large-scale air pollution models are represented by large systems of partial differential equations. After some discretization and splitting procedures these are transformed into several huge systems of ODE's, which are to be handled numerically ...

Discretization And Weak Invariants
. We consider the preservation of weak solution invariants in the time integration of ordinary differential equations (ODEs). Recent research has concentrated on obtaining symplectic discretizations of Hamiltonian systems and schemes that preserve ...

Estimating Waveform Relaxation Convergence
. Critical limitations of the waveform relaxation method concern the unsolved problems of estimating convergence and controlling the iteration. In this paper, waveform relaxation is applied to a linear, second-order model system and is studied in the ...
