“…Problems with integral boundary conditions come naturally from thermal conduction problems [29] and hydrodynamic problems [30]. In recent years there has been a lot of investigation of boundary value problems with integral boundary conditions (see for instance [31][32][33][34][35][36][37][38][39][40][41][42][43]). In particular, Boucherif [44] used the fixed point theorem in cones to consider the following problem: ⎧ ⎪ ⎪ ⎨ ⎪ ⎪ ⎩ u (t) = f (t, u(t)), 0 < t < 1, u(0)cu (0) = 1 0 g 0 (t)u(t) dt, u(1)du (1) = 1 0 g 1 (t)u(t) dt.…”

In this paper we consider sharp conditions on ω and f for the existence of C 1 [0, 1] positive solutions to a second-order singular nonlocal problem u (t) + ω(t)f (t, u(t)) = 0, u(0) = u(1) = 1 0 g(t)u(t) dt; it turns out that this case is more difficult to handle than two point boundary value problems and needs some new ingredients in the arguments. On the technical level, we adopt the topological degree method.

Consider the one-dimensional quasilinear impulsive boundary value problem involving the p-Laplace operator ⎧ ⎪ ⎪ ⎪ ⎨ ⎪ ⎪ ⎪ ⎩-(φ p (u)) = λω(t)f (u), 0 < t < 1,-u| t=t k = μI k (u(t k)), k = 1, 2,. .. , n, u | t=t k = 0, k = 1, 2,. .. , n, u (0) = 0, u(1) = 1 0 g(t)u(t) dt, where λ, μ > 0 are two positive parameters, φ p (s) is the p-Laplace operator, i.e., φ p (s) = |s| p-2 s, p > 1, ω(t) changes sign on [0, 1]. Several new results are obtained for the above quasilinear indefinite problem.
