一类q-差分第一潘勒韦方程的水银解

Quicksilver Solutions of a q-difference first Painlevé equation

Nalini Joshi

摘要:

在本文中,我们提出了新的,不稳定的解决方案,我们称之为水银的解决方案,$q$ -差分潘勒韦方程在极限作为独立的变量接近无穷大。本文考虑的具体方程是第一个潘勒韦方程($q\Pon$)的离散形式,其相空间(初值空间)是$A_7^{(1)}$型有理曲面。我们描述了四个家庭的几乎平稳的行为,但专注于最复杂的情况下,这是消失的解决方案。我们得到这个解决方案的正式幂级数展开,描述其系数的增长,并表明,而该系列是发散的,存在真正的解析解渐近这样一个系列在一定的$q$域。该方法,虽然证明了$q\Pon$,也适用于其他$q$ -差分潘勒韦方程。

英文摘要:

In this paper, we present new, unstable solutions, which we call quicksilver solutions, of a $q$-difference Painlevé equation in the limit as the independent variable approaches infinity. The specific equation we consider in this paper is a discrete version of the first Painlevé equation ($q\Pon$), whose phase space (space of initial values) is a rational surface of type $A_7^{(1)}$. We describe four families of almost stationary behaviours, but focus on the most complicated case, which is the vanishing solution. We derive this solution's formal power series expansion, describe the growth of its coefficients and show that, while the series is divergent, there exist true analytic solutions asymptotic to such a series in a certain $q$-domain. The method, while demonstrated for $q\Pon$, is also applicable to other $q$-difference Painlevé equations.
