Characterization of the spectrum of irregular boundary value problem for the Sturm-Liouville operator
Alexander Makin
We consider the spectral problem generated by the Sturm-Liouville equation with an arbitrary complex-valued potential q(x) and irregular boundary conditions. We establish necessary…

On the basis property of the root function systems of regular boundary value problems for the Sturm-Liouville operator
Alexander Makin
We consider the nonselfadjoint Sturm-Liouville operator Lu=u''-q(x)u with regular but not strongly regular boundary conditions, where q(x)is an arbitrary complex-valued summable fu…

Inverse problems of spectral analysis for the Sturm-Liouville operator with regular boundary conditions
Alexander Makin
We consider the Sturm-Liouville operator Lu=u''-q(x)u with regular but not strongly regular boundary conditions. Under some supplementary assumptions we prove that the set of poten…
