Self-adjoint extensions for a class of singular operators
(Turkish Journal of Mathematics, 2021)
In this study, we consider the domains of the minimal and maximal operators generated of singular
differential-expression-type Sturm–Liouville and obtain all self-adjoint extensions of the operator in terms of ...
Half inverse problems for the impulsive quadratic pencil with the discontinouty coefficient
(Turkish Journal of Mathematics, 2021)
In this paper, we study the inverse spectral problem for the quadratic differential pencils with discontinuity
coefficient on [0, π] with separable boundary conditions and the impulsive conditions at the point x =
