Comparison of Two Definitions of Lower and Upper Functions Associated to Nonlinear Second Order Differential Equations.
The notions of lower and upper functions play an important role in the theory of nonlinear boundary value problema. The most of them define lower and upper functions as solutions of the correspond...

Non-ordered lower and upper functions in second order impulsive periodic problems
In the paper using the lower and upper functions argument we establish new existence results for the nonlinear impulsive periodic boundary value problem to the second order differential equation. Impulses are defined at fix...

Existence results for impulsive second order periodic problems
The lower and upper functions method is extended to nonlinear impulsive periodic boundary value problems. The main attention is focused on the case of non-oredered lower and upper functions. The t...

Construction of non-constant lower and upper functions for impulsive second order periodic problems
We present conditions ensuring the existence of piecewise linear lower and upper functions for nonlinear impulsive periodic boundary value problem. This allow us to prove new existence criteria for the problem under conside...

Localization of nonsmooth lower and upper functions for periodic boundary value problems.
In this paper we present conditions ensuring the existence and localization of lower and upper functions of the periodic boundary value problem u.and..and.+ k u = f (t,u), u (0) = u (T),u.and.(0)=u.and.(T), where k is a non...

Periodic BVPs in ODEs with time singularities
We show the existence of solutions to a nonlinear singular ODE subject to periodic boundary conditions. We study the case that a well-ordered pair of lower and upper functions does not exist. Instead we assume the existence...

Solvability of discrete Dirichlet problem via lower and upper functions method
In the paper we use the lower and upper functions method to prove the existence of a solution of the Dirichlet discrete problem. The proof is based on the Brouwer fixed point theorem. The paper generalizes an earlier existe...

Periodic solution of differential equation with phi-Laplacian and state-dependent impulses
Sufficient conditions for the existence of at least one periodic solution of differential equation with phi-Laplacian and state-dependent impulses are given. The results are obtained via lower and upper functions method and...
