بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

We consider two coupled nonlinear Schrodinger equations with even, periodic boundary conditions, that are damped and ̈ ˇ quasiperiodically forced. We prove the existence of invariant manifolds with Silnikov-type dynamics that are homoclinic to a spatially independent invariant torus. Such manifolds appear to induce complex behavior in numerical experiments. q 1999 Published by Elsevier Science B...
متن کاملCoupled nonlinear Schrodinger field equations for electromagnetic wave propagation in nonlinear left-handed materials.
For isotropic and homogeneous nonlinear left-handed materials, for which the effective medium approximation is valid, Maxwell's equations for electric and magnetic fields lead naturally, within the slowly varying envelope approximation, to a system of coupled nonlinear Schrodinger equations. This system is equivalent to the well-known Manakov model that under certain conditions, is completely i...
متن کاملThe Solution of Coupled Nonlinear Burgers' Equations Using Interval Finite-difference Method
In this paper an coupled Burgers' equation is considered and then a method entitled interval finite-difference method is introduced to find the approximate interval solution of interval model in level wise cases. Finally for more illustration, the convergence theorem is confirmed and a numerical example is solved.
متن کاملSelf - Similar Solutions for Nonlinear Schrodinger Equations ∗
In this paper we study self-similar solutions for nonlinear Schrödinger equations using a scaling technique and the partly contractive mapping method. We establish the small global well-posedness of the Cauchy problem for nonlinear Schrödinger equations in some non-reflexive Banach spaces which contain many homogeneous functions. This we do by establishing some a priori nonlinear estimates in B...
