摘要
In this paper,we study a class of Sturm-Liouville problems,where the boundary conditions involve eigenparameters.Firstly,by defining a new inner product which depends on the transmission conditions,we obtain a new Hilbert space,on which the concerned operator A is self-adjoint.Then we construct the fundamental solutions to the problem,obtain the necessary and sufficient conditions for eigenvalues,and prove that the eigenvalues are simple.Finally,we investigate Green’s functions of such problem.
本文研究一类边界条件含有特征参数的Sturm-Liouville问题.首先定义一个依赖于转移条件的新内积,得到一个新的Hilbert空间,在新的Hilbert空间中研究的算子A是自共轭的.然后构造与问题相关的基本解,得到特征值的充要条件,并证明特征值是简单的.最后我们对这类问题的格林函数进行讨论.
