Abstract
Sufficient conditions are found for the existence of an upper and a lower solutions of the boundary value problem
where 
and 
are linear bounded operators, and 
and 
are continuous, generally speaking nonlinear, operators. Kamke type theorems are proved on functional differential inequalities.
Key words and phrases:: Boundary value problem for functional differential equation; upper and lower solutions; Kamke type theorem on functional differential inequalities
