Abstract: | In this paper we consider continuous-time and discrete-time waveform relaxation meth-ods for general nonlinear integral-differential-algebraic equations.For the continuous-timecase we derive the convergence condition of the iterative methods by invoking the spec-tral theory on the resulting iterative operators.By use of the implicit difference forms,namely the backward-differentiation formulae,we also yield the convergence condition ofthe discrete waveforms.Numerical experiments are provided to illustrate the theoreticalwork reported here. |
