非线性微分方程的拟精确解

Quasi-exact solutions of nonlinear differential equations

Nikolay A. Kudryashov, Mark B. Kochanov

摘要:

引入了非线性微分方程拟精确解的概念。拟精确解拓展了微分方程参数附加值精确解的思想。这些解是非线性微分方程的近似解,但它们接近精确解。建立了Kuramoto-Sivashinsky方程、Korteweg-de Vries-Burgers方程和Kawahara方程的拟精确解。

英文摘要:

The concept of quasi-exact solutions of nonlinear differential equations is introduced. Quasi-exact solution expands the idea of exact solution for additional values of parameters of differential equation. These solutions are approximate solutions of nonlinear differential equations but they are close to exact solutions. Quasi-exact solutions of the the Kuramoto--Sivashinsky, the Korteweg--de Vries--Burgers and the Kawahara equations are founded.
