把正则Sturm-Liouville问题关于特征值的性质推广到一类带转移条件的Sturm-Liouville问题中,利用prüfer变换证明了具有分离边界条件的这类问题有无穷多个实特征值,且特征值是下方有界的.
Some fundamental properties of eigenvalues for regular Sturm-Liouville problems are extended to special kind boundary value problems,which have discontinuities in the solution or its quasiderivative at an interior point. It is proved that such discontinuous problems has infinitely many eigenvalues and the eigenvalues are boundary from below.
