Riccati方程可积性的新情形

New integrability case for the Riccati equation

M. K. Mak, T. Harko

摘要:

给出了Riccati方程$dy/dx=a(x)+b(x)y+c(x)y^{2}$的一个新的可积条件.通过引入依赖于生成函数$f(x)$的辅助方程,如果系数$a(x)$、$b(x)$、$c(x)$和函数$f(x)$满足特定约束,则可以获得Riccati方程的通解。通过求解某些Riccati型微分方程的通解,验证了该方法的有效性和可靠性。简要讨论了可积性条件在频率依赖于时间的阻尼谐振子和孤立波情形中的应用。

英文摘要:

A new integrability condition of the Riccati equation $dy/dx=a(x)+b(x)y+c(x)y^{2}$ is presented. By introducing an auxiliary equation depending on a generating function $f(x)$, the general solution of the Riccati equation can be obtained if the coefficients $a(x)$, $b(x)$, $c(x)$, and the function $f(x)$ satisfy a particular constraint. The validity and reliability of the method are tested by obtaining the general solutions of some Riccati type differential equations. Some applications of the integrability conditions for the case of the damped harmonic oscillator with time dependent frequency, and for solitonic wave, are briefly discussed.
