.The spectra of non-self-adjoint Sturm-Liouville operators with distributional potentials belonging to the space W−12(0, 1) are studied. In particular, it is shown that any sequence of complex numbers obeying a specified asymptotics coincides with the spectrum of some non-self-adjoint Sturm-Liouville operator of the class under consideration. The inverse spectral problem of reconstructing an operator...
