An upper bound for the distance between a zero and a critical point of a solution of a second order linear differential equation

Almenar, Pedro; Jódar Sánchez, Lucas Antonio (Elsevier, 2012-01)

This paper presents an upper bound for the distance between a zero and a critical point of a solution of the second order linear differential equation (p(x)y¿)¿+q(x)y(x)=0(p(x)y¿)¿+q(x)y(x)=0, with p(x),q(x)>0p(x),q(x)>0. ...
Solvability of a class of nth-Order Lineal focal problems

Almenar, Pedro; Jódar Sánchez, Lucas Antonio (Vilnius Gediminas Technical University, 2017)

[EN] 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, ...
