We will expand the scope of application of a fixed
point theorem due to Krasnosel'skiĭ and Zabreiko to the family of
second-order dynamic equations described by , , with multipoint boundary conditions , , and for the purpose of establishing existence results. We will determine sufficient conditions on our function such that the assumptions of the fixed point theorem are satisfied,
which in return gives us the existence of solutions.
