Subharmonic solutions and homoclinic orbits of second order discrete Hamiltonian systems with potential changing sign

the problem of divine hiddenness

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

New explicit and Soliton Wave Solutions of Some Nonlinear Partial Differential Equations with Infinite Series Method

To start with, having employed transformation wave, some nonlinear partial differential equations have been converted into an ODE. Then, using the infinite series method for equations with similar linear part, the researchers have earned the exact soliton solutions of the selected equations. It is required to state that the infinite series method is a well-organized method for obtaining exact s...

Infinite Resonant Solutions and Turning Points in a Problem with Unbounded bifurcation

We consider an elliptic equation −∆u + u = 0 with nonlinear boundary conditions ∂u ∂n = λu + g(λ, x, u), where g(λ, x, s) s → 0, as |s| → ∞. In [1, 2] the authors proved the existence of unbounded branches of solutions near a Steklov eigenvalue of odd multiplicity and, among other things, provided tools to decide whether the branch is subcritical or supercritical. In this work we give condition...

Existence and Multiplicity Results of Homoclinic Solutions for the DNLS Equations with Unbounded Potentials

and Applied Analysis 3 DNLS equation is one of the most important inherently discrete models, which models many phenomena in various areas of applications see 2–4 and reference therein . For example, in nonlinear optics, DNLS equation appears as a model of infinite wave guide arrays. In the past decade, the existence and properties of mobile discrete solitons/breathers in DNLS equations have be...
