提出一种求解非线性问题的新方法
Presenting a new method for the solution of nonlinear problems
摘要:
我们提出了一种解决(振荡)非线性问题的方法。它是基于线性增量展开的Lindstedt-Poincaré方法的应用。通过将其应用于Duffing方程,我们表明,我们的方法大大提高了由简单的Lindstedt-Poincaré方法给出的近似。
英文摘要:
We present a method for the resolution of (oscillatory) nonlinear problems. It is based on the application of the Linear Delta Expansion to the Lindstedt-Poincaré method. By applying it to the Duffing equation, we show that our method substantially improves the approximation given by the simple Lindstedt-Poincaré method.
