Abstract:
In this paper, by using certain fixed points theorem based on the degree theory, some sufficient conditions for the existence of solutions of initial and boundary value problems for n order ordinary differential equations in Banach spaces are given, moreover, the authors get existence of maximal and minimal solutions. The results are extension of reference [1-2].
Key words: Boundary value problems, Set-contract operators, Fixed points, Non- compactness measures.
