Generalization of Hypervirial and Feynman-Hellmann Theorems for Singular Potentials
T. Nadareishvili, A. Khelashvili
Using well-known methods we generalize (hyper)virial theorems to case of singular potential. Discussion is performed for most general second order differential equation, which invo…

Some Problems of Self-Adjoint Extension in the Schrodinger equation
T. Nadareishvili, A. Khelashvili
The Self-Adjoint Extension in the Schrodinger equation for potentials behaved as an attractive inverse square at the origin is critically reviewed. Original results are also presen…
