摘要
Using a global existence result due to A. Granas et al. [7] and the barrier strips technique, we study the solvability of the boundary value problem x('") = f(t, x, x', x ''), x(0) = A, x'(0) = B, x"(1) = C where f :[0,1] x R-3 -> R is continuous. The obtained sufficient conditions guarantee the existence of at least one solution in C-3 [0,1] which may be nonnegative, monotone and convex.
