A singularly, perturbed system of differential equations with
degenerate matrix at the derivative is considered. The existence and
construction of the periodic solutions are investigated in critical case.
For the analysis of these algorithms the apparatus of Lyapunov's finite
majorizing equations is used. An implementation of this method is given
in two examples.
