Abstract

We consider the boundary value problem

(1)npy(n=λF(t,y,y,,y(p)   (n2,t(0,1))(–1)^{n–p}y^{(n} = \lambda F(t, y, y', \dots, y^{(p)} \ \ \ (n ≥ 2, t \in (0,1))
y(i)(0)=0   (0ip1)y^{(i)} (0) = 0 \ \ \ (0 ≤ i ≤ p–1)
y(i)(1)=0   (pin1)y^{(i)} (1) = 0 \ \ \ (p ≤ i ≤ n–1)

where λ>0\lambda > 0 and 1pn11 ≤ p ≤ n–1 are fixed. The values of λ\lambda are characterized so that the boundary value problem has a positive solution. We also establish explicit intervals of λ\lambda. Examples are included to dwell upon the importance of the results obtained.
