The article is devoted to the existence of positive solutions to nonlinear retarded functional-differential equations. Some criteria of existence and some comparison results are proved. The existence of positive and oscillation solutions to the equation \(x'(t)=-a(t)x(t-\tau)\) in the critical case is proved.
