关于自共轭微分型的判定方法

Intoduce to the method of Decide for Self Adjoint Differential Expression

利用 Krall 公式,讨论了任—2n 阶微分型 L(y)乘以乘子 f(x)后,f(x)L(y)是否构成自共轭微分型的问题,并给出了乘子 f(x)的求法。

The paper applies Krall formula to discuss the question about any differential expression of order 2n L(y) by multiplying it with multiplicator f(x) and to see if f(x)L(y) can be made formully self- adjoint diffential expression.And it gives a method which looks for multiplicator f(x).
