利用非线性Rayleigh商求Nehari流形方法的极值

On extreme values of Nehari manifold method via nonlinear Rayleigh's quotient

Yavdat Il'yasov

摘要:

研究了巴拿赫空间$W$中$ D_u T(u)-λD_u F(u)=0 $型方程的Nehari流形方法的适用条件,其中$λ$为实参数.我们的研究是基于非线性问题的瑞利商理论的发展。证明了Nehari流形方法中参数$λ$的极值可以通过相应的非线性广义Rayleigh商的临界值来求出。在本文的主要部分,我们提供了一些一般性的结果,这种关系。应用于几类非线性椭圆方程和方程组。

英文摘要:

We study applicability conditions of the Nehari manifold method for the equation of the form $ D_u T(u)-λD_u F(u)=0 $ in a Banach space $W$, where $λ$ is a real parameter. Our study is based on the development of the theory Rayleigh's quotient for nonlinear problems. It turns out that the extreme values of parameter $λ$ for the Nehari manifold method can be found through the critical values of a corresponding nonlinear generalized Rayleigh's quotient. In the main part of the paper, we provide some general results on this relationship. Applications are given to several types of nonlinear elliptic equations and systems of equations.
