abstract = {<p style="text-align: justify;">A singularly perturbed boundary value problem with weak nonlinearity in the case when the degenerate equation has a multiple root is studied.
The asymptotic approximation of the solution is constructed by the modified
boundary layer function method. Based on the comparison principle, there
exist multizonal boundary layers in the neighborhood of the endpoints. The
existence of a solution is proved by using the method of asymptotic differential
inequalities.</p>},
