Eigenvalue asymptotics for Sturm–Liouville operators with singular potentials

We derive eigenvalue asymptotics for Sturm–Liouville operators with singular complex-valued potentials from the space , 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.
