“…0 + y(t) + λI p 1 − I q 0 + h t, y(t) = f t, y(t) , t ∈ J := [0, 1], y(0) = y(ξ) = 0, y(1) = δy(µ), 0 < ξ < µ < 1, where 1 < α 2, 0 < β 1 and p, q > 0, f, h : [0, 1] × R → R are given continuous functions, and δ, λ, µ ∈ R are constants. At the same time, the differential equations with delay have many successful applications in the fields of communication engineering, population control and so on; see [1,9,20,21,26,28,35].…”
