While convergence of polynomial chaos approximation for linear equations is relatively well understood, a lot less is known for non-linear equations. The paper investigates this convergence for a particular equation with quadratic nonlinearity.

翻译：虽然对线性方程式多边混乱近似值的趋同相对理解,但对于非线性方程式则不那么为人所知。 本文对特定方程式与二次非线性等同值的趋同性进行了调查。
