Abstract
We investigate the analytic properties of solutions of a system of two first-order nonlinear differential equations with an arbitrary parameter \(l\) associated with an overdamped Josephson model. We reduce this system to a system of differential equations that is equivalent to the fifth Painlevé equation with the sets of parameters
$$\biggl(\frac{(1-l)^2}{8}, -\frac{(1-l)^2}{8},0,-2\biggr), \; \biggl(\frac{l^2}{8}, -\frac{l^2}{8},0,-2\biggr).$$We show that the solution of the third Painlevé equation with the parameters \((-2l, 2l-2,1,-1)\) can be represented as the ratio of two linear fractional transformations of the solutions of the fifth Painlevé equation (with the parameters in the above sequence) connected by a Bäcklund transformation.
论与约瑟夫森模型相关的两个非线性微分方程系的解的性质
摘要 我们研究了与过阻尼约瑟夫森模型相关的带有任意参数 \(l\) 的两个一阶非线性微分方程系统解的解析性质。我们把这个系统简化为一个微分方程系统，它等价于参数集为 $$\biggl(\frac{(1-l)^2}{8}, -\frac{(1-l)^2}{8},0,-2\biggr), \; \biggl(\frac{l^2}{8}, -\frac{l^2}{8},0,-2\biggr) 的第五个潘列夫方程。$$ 我们证明，参数为 \((-2l,2l-2,1,-1)\)的第三个潘列夫方程的解可以表示为第五个潘列夫方程的解（参数为上述序列中的参数）的两个线性分数变换之比，这两个线性分数变换通过贝克隆变换连接起来。
