Solvability of a Class of N -th Order Linear Focal Problems

Autor: Pedro Almenar, Lucas Jodar

Publikováno v: Mathematical Modelling and Analysis, Vol 22, Iss 4 (2017)

This paper presents a recursive method which yields necessary and sufficient conditions for the existence of solutions of a class of n-th order linear focal boundary value problems in the interior of a given interval, in the form of integral inequali
