On solutions of some fractional -point boundary value problems at resonance.
On solutions of the vector functional equation y(...(x)) = f(x) * A * y(x).
On solving certain differential equations with variable coefficients.
On solving systems of differential algebraic equations
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.
