A note on discrete waveform relaxation of stiff index-1 differential algebraic equations & symposia

The paper studies the discrete waveform relaxation processes based on Runge-Kutta methods for solving stiff differential-algebraic systems of index-1. The new convergence results are obtained, which are relevant in applications to nonlinear stiff differential-algebraic systems of index-I. The existence and uniqueness of the solutions are derived.
