points in C(I), which are exactly the solutions of problem (4).
Claim 2: Every solution x of (4) satisfies α ≤ x ≤ β on I and, therefore, it
is a solution of (1) in [α, β]. First, ... [2–7] which deal with existence results for this kind of prob-
lems. For the qualitative study of this type of problems we can cite the
