研究了以Painleve-II方程为连续极限的三点映射。限定词“alternate”是因为已经存在另一种离散形式的。我们提出了这个离散方程的Lax对,以及它的自动Backlund变换。特殊的合理的解决方案,以及解决方案方面的(离散)艾里函数获得的参数的方程的特定值。
We study a three-point mapping that has the Painleve-II equation as continuous limit. The qualifier `alternate' is due to the fact that there already exists another discrete form of . We present the Lax pair for this discrete equation, as well as its auto-Backlund transform. Special rational solutions as well as solutions in terms of the (discrete) Airy function are obtained for particular values of the parameter of the equation.
