一类四阶非齐次线性奇异摄动的边值问题

A class of fourth-order non-homogeneous linear singular perturbed boundary value problem

讨论一类四阶非齐次线性奇异摄动边值问题的边界值方法 .给出了这个问题的误差估计 ,从而证明了边界值方法的可行性 .最后用数值例子证实了该方法的有效性 .

A boundary value method for a class of fourth order non homogeneous linear singularly perturbed boundary value problem is discussed,and error estimate for the problem is given,which provides a theoretical justification for the method.Finally,numerical result is presented for a problem with constant coefficients to confirm the method is effective.
