Picard method; Seidel method; system of differential algebraic equations; convergence; successive approximations; differential algebraic equations; comparison method; Picard iterations
In the paper the comparison method is used to prove the convergence of the Picard iterations, the Seidel iterations, as well as some modifications of these methods applied to approximate solution of systems of differential algebraic equations. The both linear and nonlinear comparison equations are emloyed.
