Abstract
This paper deals with boundary value problems for second-order
differential equations with deviating arguments. Some sufficient conditions
are formulated under which such problems have quasisolutions or a unique
solution. A monotone iterative method is used. Examples with numerical
results are added to illustrate the results obtained.
