Abstract
Homotopy methods are used to find sufficient conditions for the solvability of nonlinear boundary value problems of the form (φ(u′))′ = f(t, u, u′), g(u(α), φ(u′(β))) = 0, where (α, β) = (0, 1), (1, 0), (0, 0) or (1, 1), φ is a homeomorphism from the open ball B(a) ⊂ ℝ<sup>n</sup> onto ℝ<sup>n</sup>, f is a Carathéodory function, g: ℝ<sup>n</sup> × ℝ<sup>n</sup> →ℝ<sup>m</sup> is continuous and m ≤ 2n. © 2013 Springer Basel.
