摘要翻译:
我们分别给出了painlev方程$P_{V}、P_{IV}、P_{III}和$P_{II}的对称性的一种新方法。此外,我们分别对painlev方程的四阶类似物作了自然推广,它们在保持对称性的意义上是自然的。

英文摘要:
  We give a new approach to the symmetries of the Painlev\'e equations $P_{V},P_{IV},P_{III}$ and $P_{II}$, respectively. Moreover, we make natural extensions to fourth-order analogues for each of the Painlev\'e equations $P_{V}$ and $P_{III}$, respectively, which are natural in the sense that they preserve the symmetries.
