摘要研究了带小参数的Painlevé-2方程的一个特殊渐近解。该解有一个临界点t ∞对应于一个分叉现象。当t < t ∞时,构造的解变化缓慢,当t > t ∞时,解振荡非常快。我们详细研究了过渡层,并获得了一个光滑的渐近解,使用一系列的缩放和匹配程序。
Abstract A special asymptotic solution of the Painlevé-2 equation with small parameter is studied. This solution has a critical point t ∗ corresponding to a bifurcation phenomenon. When t < t∗ the constructed solution varies slowly and when t > t ∗ the solution oscillates very fast. We investigate the transitional layer in detail and obtain a smooth asymptotic solution, using a sequence of scaling and matching procedures.
