通过类比连续Painleve-II方程,我们提出了特殊的解决方案的离散Painleve-II(d-PII)方程。这些解决方案是一个合理的和特殊的功能(艾里)型。我们的分析是基于双线性形式主义,使我们能够获得的tau函数的d-PII。得到了两种不同形式的双线性d-PII,我们表明,它们可以通过一个简单的规范变换。
By analogy to the continuous Painleve-II equation, we present particular solutions of the discrete Painleve-II (d-PII) equation. These solutions are of a rational and special function (Airy) type. Our analysis is based on the bilinear formalism that allows us to obtain the tau -function for d-PII. Two different forms of bilinear d-PII are obtained and we show that they can be related by a simple gauge transformation.
