This paper studies the existence of periodic solutions of a third order iterative differential equation. The main tool used here is Krasnoselskii-Burton’s fixed point theorem dealing with a sum of two mappings, one is a large contraction and the other is

Optimal Perturbation Iteration Method for Bratu-Type Problems [PDF]
In this paper, we introduce the new optimal perturbation iteration method based on the perturbation iteration algorithms for the approximate solutions of nonlinear differential equations of many types. The proposed method is illustrated by studying Bratu-

Lyapunov-type inequalities for certain higher-order half-linear differential equations
In this paper, we will establish some new Lyapunov-type inequalities for some higherorder half-linear differential equations with anti-periodic boundary conditions.

On sums of powers of zeros of polynomials [PDF]
Due to Girard's (sometimes called Waring's) formula the sum of the $r-$th power of the zeros of every one variable polynomial of degree $N$, $P_{N}(x)$, can be given explicitly in terms of the coefficients of the monic ${\tilde P}_{N}(x)$ polynomial ...

Existence and multiplicity of solutions for a Dirichlet problem involving the discrete p(x)-Laplacian operator [PDF]
In the present paper, using the three critical points theorem and variational method, we study the existence and multiplicity of solutions for a Dirichlet problem involving the discrete p(x)-Laplacian ...

Lower bounds for eigenvalues of the one‐dimensional p‐Laplacian
We present sharp lower bounds for eigenvalues of the one‐dimensional p‐Laplace operator. The method of proof is rather elementary, based on a suitable generalization of the Lyapunov inequality.

The paper deals with the existence and non-existence of solutions of the following strongly nonlinear non-autonomous boundary value problem: (P){(a(t,x(t))Φ(x′(t)))′=f(t,x(t),x′(t))a.e. t∈R,x(−∞)=ν−,x(+∞)=ν+ with ν−

Periodic solutions to a generalized Liénard neutral functional differential system with p-Laplacian
By means of the generalized Mawhin’s continuation theorem, we present some sufficient conditions which guarantee the existence of at least one T-periodic solution for a generalized Liénard neutral functional differential system with p-Laplacian.

Weak homoclinic solutions of anisotropic discrete nonlinear system with variable exponent
We prove the existence of weak solutions for an anisotropic homoclinic discrete nonlinear system. Suitable Hilbert spaces and norms are constructed. The proof of the main result is based on a minimization method.

Nonresonance conditions for fourth order nonlinear boundary value problems
This paper is devoted to the study of the problem We assume that f can be written under the form where r is a bounded function. We obtain existence conditions related to uniqueness conditions for the solution of the linear problem
