第四类潘勒韦方程的Clarkson-McLeod解的奇异渐近性

Singular asymptotics for the Clarkson-McLeod solutions of the fourth Painlevé equation

Jun Xia, Shuai-Xia Xu, Yu-Qiu Zhao

摘要:

我们考虑第四类潘勒韦方程的Clarkson-McLeod解。这类解的行为类似于$κD_{α-\frac{1}{2}}^2(\sqrt{2}x)$和$x\rightarrow +\infty$,其中$κ$是任意实常数,$D_{α-\frac{1}{2}}(x)$是抛物柱面函数。利用Deift-Zhou非线性最速下降法,得到了当$κ\left( κ-κ^*\right )>0$为某一实常数$κ^*$时,解为$x\to-\infty$的奇异渐近性.连接公式也被显式计算。这证明并推广了Clarkson和McLeod的猜想:当参数$κ>κ^*>0$时,Clarkson-McLeod解在负实轴上有无穷多个简单极点.

英文摘要:

We consider the Clarkson-McLeod solutions of the fourth Painlevé equation. This family of solutions behave like $κD_{α-\frac{1}{2}}^2(\sqrt{2}x)$ as $x\rightarrow +\infty$, where $κ$ is an arbitrary real constant and $D_{α-\frac{1}{2}}(x)$ is the parabolic cylinder function. Using the Deift-Zhou nonlinear steepest descent method, we obtain the singular asymptotics of the solutions as $x\to-\infty$ when $κ\left( κ-κ^*\right )>0$ for some real constant $κ^*$. The connection formulas are also explicitly evaluated. This proves and extends Clarkson and McLeod's conjecture that when the parameter $κ>κ^*>0$, the Clarkson-McLeod solutions have infinitely many simple poles on the negative real axis.
