在空间W2α−1(0,1),α∈[0,1]和Dirichlet或Neumann-Dirichlet边界条件下,我们得到了具有奇异复值位势的Sturm-Liouville算子的特征值渐近性.我们还将所得结果应用于从这两个谱中恢复势的逆谱问题。
We derive eigenvalue asymptotics for Sturm–Liouville operators with singular complex-valued potentials from the space W2α−1(0,1), α∈[0,1], and Dirichlet or Neumann–Dirichlet boundary conditions. We also give application of the obtained results to the inverse spectral problem of recovering the potential from these two spectra.
