Sturm comparison theorems via Picone-type inequalities for some nonlinear elliptic type equations with damped terms [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper, we establish a Picone-type inequality for a class of some nonlinear elliptic type equations with damped terms, and obtain Sturmian comparison theorems using the Picone-type inequality.

Sturmian comparison theorem for half-linear second-order differential equations

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 1995
Let φ:ℝ→ℝ be defined by φ(s) = |s|p−2s, with p > 1 a fixed number. We extend Sturm Comparison Theorem of the linear differential equationto the nonlinear differential equationby using the Wirtinger inequality. A Lyapunov inequality and some oscillation criteria of (E) are also given.

A Sturmian theorem for recessive solutions of linear Hamiltonian difference systems

open access: yesApplied Mathematics Letters, 1999
The main result of the paper is a Sturmian-type separation theorem for the recessive solutions of linear Hamiltonian difference systems. The assumptions on the Hamiltonian systems allow to include the study of Sturm-Liouville difference equations of ...

Generalized Picone's identity and its applications

open access: yesElectronic Journal of Differential Equations, 2013
In this article we give a generalized version of Picone's identity in a nonlinear setting for the p-Laplace operator. As applications we give a Sturmian Comparison principle and a Liouville type theorem.

Picone-type inequality and Sturmian comparison theorems for quasilinear elliptic operators with p(x)-Laplacians

open access: yesElectronic Journal of Differential Equations, 2012
A Picone-type inequality for quasilinear elliptic operators with mixed nonlinearities and with p(x)-Laplacian is established, and Sturmian comparison theorems are derived on the basis of the Picone-type inequality.

Novel Stream Ciphering Algorithm for Big Data Images Using Zeckendorf Representation

open access: yesWireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
Big data is a term used for very large data sets. Digital equipment produces vast amounts of images every day; the need for image encryption is increasingly pronounced, for example, to safeguard the privacy of the patients’ medical imaging data in cloud disk.

Rayleigh principle for time scale symplectic systems and applications

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper we establish the Rayleigh principle, i.e., the variational characterization of the eigenvalues, for a general eigenvalue problem consisting of a time scale symplectic system and the Dirichlet boundary conditions.

Existence and Nonexistence of Solutions for Fourth‐Order Nonlinear Difference Boundary Value Problems via Variational Methods

open access: yesDiscrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018
This paper is concerned with boundary value problems for a fourth‐order nonlinear difference equation. Via variational methods and critical point theory, sufficient conditions are obtained for the existence of at least two nontrivial solutions, the existence of n distinct pairs of nontrivial solutions, and nonexistence of solutions.
