On recovering quadratic pencils with singular coefficients and entire functions in the boundary conditions
Maria Kuznetsova
In the paper, we study an inverse spectral problem for quadratic pencils of the Sturm--Liouville operators with singular coefficients and entire functions in the boundary condition…

Inverse problem for Sturm--Liouville operators with frozen argument on closed sets
Maria Kuznetsova
In the paper, we study the problem of recovering the potential from the spectrum of the Dirichlet boundary value problem for a Sturm--Liouville equation with frozen argument on a c…
