关于“非线性特征值问题”

On "Nonlinear eigenvalue problems"

Oliver S. Kerr

摘要:

Bender,Fring和Komijani \cite{BenderEtAl:2014}研究了$y'(x)=\cos[πx y(x)]$解的渐近性态。例如,他们发现了初始值$y(0)=a$和溶液显示的最大值数量之间的关系。我们提出了另一种推导的渐近结果,着眼于解决方案中的区域$x<y$和$x>y$,并证实了以前发现的行为较大的值$a$。该方法使用区域$x<y$中振荡行为的小振幅和高频率。

英文摘要:

The asymptotic behaviour of solutions to $y'(x)=\cos[πx y(x)]$ was investigated by Bender, Fring and Komijani \cite{BenderEtAl:2014}. They found, for example, a relation between the initial value $y(0)=a$ and the number of maxima that the solution exhibited. We present an alternative derivation of the asymptotic results that looks at the solutions in the regions $x<y$ and $x>y$, and confirms the behaviour found previously for larger values of $a$. This method uses the small amplitude and high frequency of the oscillatory behaviour in the region $x<y$.
